15th October 2025: The Antiqvarivm at Complvtvm (Alcalá de Henares, Spain)

Though October is usually my holiday month and I can go on long trips (such as Türkiye in 2024), this year I came across an unexpected project. That means extra money, but less time, and even though I had a blast in Loarre and Zaragoza, it was not really a holiday. I decided to take a day trip before the weather turned and work took over. I mulled over several ideas, and in the end I came down with two – basically an urban day trip or rural day trip, and in the end, I decided to go for the urban trip. A while back (longer than I thought), I visited Complutum, the archaeological remains of the Roman town which stood underneath what today is Alcalá de Henares. That time, one of the main buildings was closed off due to archaeological works, but it was now open. Furthermore, the city has recently opened a new museum. These factors pushed me to go there in the end. It helped that I needed to do some shopping.

The Romans first established provinces in Hispania around the 200 BCE, after the second Punic War. In the year 19 BCE, the first Roman Emperor, Augustus, formally added the Iberian Peninsula to the Empire. Despite some strife, Spain remained part of the Roman Empire until the latter collapsed in the 5th century CE. There’s a lot that Spaniards owe to the Romans, including a good road system, aqueducts and waterways, and lots of mosaics, a good number of them in the MARPA.

The city of Complutum was founded in the 1st century CE, and greatly expanded through the 3rd century. At the turn of the 2nd century, during the Christian persecution, two children were killed and are now considered martyrs. Unlike other sites, the city was never really abandoned, just gave way to newer civilisations and it was built over. During the 19th century, the archaeological sites were pillaged, and between 1970 and 1974 a lot of the remains were destroyed to build new dwellings. The archaeological site received protection from the 1985 Heritage Law, and further recognition as Cultural Asset (BIC) in 1992.

I did not feel like driving in the chaotic Alcalá de Henares traffic, especially now that they’re having construction along the main avenues, so I parked the car a bit away and walked – this is something I do when I go to the centre. The weather was nice so the 40 minutes did not feel long. I visited the three main spots: the larger archaeological site Ciudad Romana de Complutum, the new museum Antiquarium and, since I was not crazily far, the house Casa de Hippolytus.

I first headed off towards the Antiquarium, the “new” museum. I call it new because it has opened in 2025, though the building had been erected over a decade earlier at the very least. It is a large space which hosts some of the elements recovered in recent excavations – though due to the general pillage of the site in earlier centuries and all the losses due to modern construction, it is not as rich as it should be in its own right. There are two key elements in the museum – room F of the House of Griffins, and the mosaic of the Winning Chariot Racer.

The House of Griffins, Casa de Los Grifos, is considered the best example of Roman mural painting in Spain. It was a large domus of 17 rooms at least. It was built in the 1st century CE, but it burnt and collapsed in a fire at the beginning of the 3rd century. Outside of Pompeii, it’s probably one of the best preserved houses I’ve ever seen, even if it is in two places. The room moved to the Antiquarium names the house. Amongst other mythological representation, the entrance is guarded by two griffins, animals with the head of an eagle and the body of a lion, facing each other.

The other key exhibit is the mosaic El Auriga Victorioso, which was found in an outskirts villa where Romans bred horses. The museum has woven a whole story around the mosaic, to the point that you could actually believe that everything they tell you about the hypothetical character is based on facts instead of just speculation.

Outside the building there is a fountain Fuente del Juncal, part of the water distribution system of the city, channelling water from the nearby river Río Henares. It was heavily restored in the 19th century, so there is no way to know how it looked originally.

After the museum, I headed to the actual city to see the rest of the House of Griffins in situ, in the Ciudad Romana de Complutum Roman city. The vermilion walls which still stand were probably painted with cinnabar from Almadén. However, it was difficult to see from afar what parts were original and what had been restored. Other spaces that can be seen throughout the city are the foundations of a dwelling block, the forum and the therms. Two spaces require a lot of imagination – a piece of wall is supposed to be where the child martyrs Justus and Pastor were killed, and the restored auguraculum, where the oracles worked.

The last time I visited Complutum, the Antiquarium had not opened and the House of Griffins was closed due to excavation works there. I did visit the other house Casa de Hippolytus, which was completely accessible. However, since I was nearby, I decided to get there again. They have a very cool mosaic with Mediterranean fishery themes, including a moray eel, an octopus, a dolphin and a very-accurate lobster. Interestingly enough, Hippolytus was not the owner of the house, but the artist who signed this mosaic.

I headed back towards the shopping centre where I had left the car and went into a The Good Burger there, because I am very partial to their Cheese Lovers hamburger (and their soda refill policy). They had a menu option so I decided to go with the chips – I had the choice between chips with salt and chips with salt (and that’s not my typo). The burger in question is garnished with American cheese, goat cheese, Gorgonzola cheese, poached onion and honey-and-mustard sauce. Lots and lots of cheese, for real.

I did not do much afterwards. I bought a few items I needed and headed to the car to drive home.

26th November 2024: Another Concavenator visit (Alcalá de Henares, Spain)

I had to run some errands in Alcalá de Henares in the afternoon, so I decided I would get there in the morning, and walk to the Archaeology and Palaeontology museum Museo Arqueológico y Paleontológico de la Comunidad de Madrid, MARPA. The exhibition “Dragon HuntersCazadores de Dragones was still running and since it was a random weekday morning, I thought it would be empty.

I was right, it was deserted enough that the security guard looked at me weirdly. Yes, I’ve been there before. Twice. I hope to be back at least once more before the exhibit closes in January 2025. The security guard should not be remembering me, I did nothing weird. Taking a few hundred photographs of a fossil is completely normal.

Why am I so obsessed about the Concavenator? Well, one does not always have such a unique fossil so handy, and for free. Furthermore, the usual home of the Concavenator does not allow pictures. And lastly, I’m a nerd. The species Concavenator corcovatus was described in 2010 by Francisco Ortega, Fernando Escaso, and José Luis Sanz from a single skeleton found at Las Hoyas site in 2003. The specimen was officially catalogued as MCCM-LH 6666. The animal was a medium-sized carcharodontosaurid. Carcharodontosauria, which included the likes of Giganotosaurus, Mapusaurus or Carcharodontosaurus, were a group of large theropods from the Cretaceous period. The skeleton was almost complete, with the tail and neck contorted in rigor mortis. The fossil shows two things that make it special – a hump or sail created by the spines of the back vertebrae, and the fact that some pigments were found on the fossil. Not unique but rare enough findings include impressions of skin and scales, and smaller bones in the belly area, rests of undigested dinner. On the arm bones there are insertions for ligaments similar to those that modern birds have at the insertion of feathers.

Concavenator corcovatus

The Concavenator lived around 125 million years ago, in an area of wetlands. Its teeth, general shape (it walked on its two hindlegs and had small-ish arms), along with the remains of animals that it had eaten, tell us it was a carnivore, and its placement in the carcharodontosaurid family, that it was a predator. However, no large predator is known for rejecting a good scavenging feed. The spikes or hump on its back, above the hips, can be clearly seen on the fossil, but nobody has any idea of what it was for – speculations have been made for communication means, fat deposits and thermoregulation. When alive, the animal would have been around 5 metres long, two metres tall, and 450 kilograms heavy.

All that to end up being dug up and named… Pepito, which is the diminutive of the diminutive of the Spanish version of Joseph. The equivalent of Joseph would be José, nicknamed Pepe, and changing the last “e” into “ito” – the suffix for small – would yield to something like Joey. So this magnificent predator was either named after a mini-mini-Joseph, or a small meat sandwich, which is also referred to as a pepito. Seriously, what happened to the illustrious tradition of Boaty McBoatface? This would have been a glorious Toothy McToothface (“Spanishised” as Dientito Caradientez or something).

Anyway, after the visit I dropped by the museum shop to buy myself some Concavenator-related merchandise. When was there the first time, I bought the exhibition catalogue, but since then they had received some silly cute items – I bought a pin, a badge, and a magnet, just because I could. Maybe as the exhibit draws closer to the end there will be discounts on other things…

I left the museum and decided that since it was way past 14:00, I should grab a bite to eat. As I had parked my car next to a shopping centre, I headed there with the idea of some Asian food. However, there is a burger joint that usually has a long queue and that some friends had told me was really good – as good as fast food can be, I guess. It is called TGB – The Good Burger. It is supposed to serve “NYC style gourmet hamburgers”. The place was empty, so I decided to give it a try.

I ordered a “Cheese Lovers” burger, which consisted of a beef patty, American cheese, goat cheese, Gorgonzola, sautéed onions, arugula and honey mustard sauce. It was… very cheesy. It was nice, but nothing I feel I must try again, especially when there are cheaper options in the shopping centre. And sushi. But at least, I satisfied my curiosity before I went off towards all my dull, grown-up errands which I shall not bore you with…
