Tonight I present a very rare photo from inside Prague's Invalidovna. It was a military veteran's hospital built in the 1730s. The building saw prolonged use as a hospital/veteran's home until the 1930s. After that the Czech army took over the building and used it as an archive. It was damaged by an epic flood in 2002 and is set to undergo an at least six year restoration; after which there will be tours and it will likely house offices for NGO and Non-Profit organizations. One weekend each year the building is opened to the public for tours so here is a rare look inside at the chapel.
