The House of the Four Idiots

Mapped
This is a building on námĕstí Svobody that is known as The House of the Four Idiots, Dům u čtyř mamlasů in Czech. It was built for one “of Brno's richest nineteenth-century Jewish industrialists.” p358, The Rough Guide to the Czech & Slovak Republics

Now it's just one of a warren of commercial buildings, like everything else on náměstí Svobody.
