A visit to the cathedral in Chartres is always worth it. It was built between 1194 and 1250 - and I read in Wikipedia it the fifth one to have occupied that site - the first was built in the 4th century. This cathedral is in very good shape and at least it didn't have scaffolding on it. There was lots of great stained glass, gargoyles, and statuary. We'd wanted to go on Malcolm Miller's English language tour that afternoon, but it didn't happen - it usually does both in the morning and the afternoon.
