A factoid that was once uncited in Wikipedia claims that the main buildings in Manresa are all built from rubble, the reason being that Napoleon and his troops demolished and burned the city as they retreated, and so it was literally rebuilt in place from the remnants. I could definitely see that was a plausible story, too. In the Southwestern United States, we don't have any buildings that were built, let alone demolished, in the early 19th century.
