Riga Dome Cathedral is the largest medieval church in the Baltic States, founded in 1211 and the seat of the Archbishop of Latvia. The imposing cathedral combines Romanesque, Gothic and Baroque elements. Its greatest treasure is the famous Walker organ with 6718 pipes, one of the largest instruments in Europe. A short Concerto Piccolo is performed daily at noon for 20 minutes, with longer evening concerts on Fridays at 19:00. The adjacent cloister is included in the entry price and features beautiful 13th-century arcades
