I spent 4 days in amazing Tarragona, Catalonia, for the Spanish-Portuguese Microscopy Society meeting. Our hosts were gracious, the meeting was interesting, I was very pleased with the lecture I gave; an overall great visit. Best of all, our time coincided with the Santa Tecla Festival; their big blowout annual fest. Catalans are proud people with many old traditions and we were exposed to a lot of them. Dancing and exhibitions in the streets, concerts, human castle-building (see pictures). We were also given a guided tour of the city, which is built among and within the ancient Roman city of Tarraco, which was the Roman capital of its Iberian empire, and is now a UNESCO World Heritage Site.
Our hotel was right in one of the central squares, the Placa de la Font. Our room faced the Plaza, and man was it noisy!
I've posted a lot of pictures from Tarragona; you can find them on google+
