Clunia excavation: Full moon at Tiermes


Last weekend we visited Tiermes, another abandoned Roman city in the region. Mike and Aixa excavated here years ago and guided the rest of us through the red sandstone cliffs and foundations of the ancient city.

There are remnants of old roads, irrigation tunnels, and an amphitheatre.

Mike told ghost stories in the tunnel, with predictable reactions.


There’s also a small Romanesque chapel on the site, with this capital which appears to depict a jousting match. Guess who won?

After touring the site, we took part in the full moon festival hosted by Manolo at the Venta Tiermes, togas and all. Thanks to Patricia from Soria who later sent me this photo of one of my jumps across the bonfire.

Clunia excavation: The caliphate fortress of Gormaz


Last weekend we visited the caliphate fortress of Gormaz, which occupies a massive hill overlooking vast swathes of farmland in the province of Soria.

The fortress hosted Moorish forces during most of the tenth century as they skirmished with Christian armies to the north of the Duero river.

Christian armies took control of it during the fighting, but it wasn’t until 1060 that they held it definitively.

Clunia excavation: Making discoveries


Knowing where you discover something is important: archaeologists survey the base of the theatre at Clunia.

Rosa brushes off one of two chunks of a statue bust in a room built alongside the entrance to the amphitheatre. Shrine? Looters’ storage area? Green room? Nobody knows.
This is Joan, the site director’s son, guarding a bronze blob he and I found in the middle of a ramp leading into the amphitheatre. The first clues were some green-tinged rocks. Beneath them some chunks of green and rust-colored metal sat encased in gray dirt and rock. It was hard to separate them so instead we worked around them, widening the pit until it got to about half a meter deep and we could see that the bronze didn’t go any lower. The blob rested on some old roof tiles and ash and burnt wood. Before removing it, Joan wrapped it in gauze and painted it with acetone to hold it together.

Shannon wriggles her nose while Francesc and Aixa hash out the next steps for uncovering steps on a ramp into the backstage area of the theatre.

Greening Mortar With Olive Waste

The cement industry is one of the world’s largest producers of atmospheric carbon dioxide. The reason is that cement’s calcium carbonate releases the greenhouse gas. Now researchers have shown that they can replace up to 10% of the cement in mortar mixtures without harming the strength of the widely used masonry paste. The cement’s replacement is environmentally friendly, to boot: a waste product from olive oil production (Environ. Sci. Technol., DOI: 10.1021/es200968a).
