Charlie's Church, located on the south side of Karlsplatz, is a baroque church building with a green oval dome. The sides of the church are engraved with bas-relief columns and are very delicate. The church is chargeable, 8 euros / person. There is a waiter who sells concert tickets at the entrance of Charlie's Church. The price is relatively high. I think it would be enough to feel it once in the Golden Hall. The entrance to the church is Karl Square. It is quite deserted in the morning. It is very lively at night when there is a Christmas market.
