This building is The Antonín Dvořák Museum in Prague, He lived from 1841 to 1904 and was a great Czech composer. Here are only three of his many maserpieces Slavonic Dance, The New Symphony and Rusalka.
It is very nice museum dedicated to his life and work and in the backyard you can rest in a very interesting garden.
Nice entry, thank you so much for your contribution to the challenge. Tomas
