Vibrant Vecrīga, the old town, is home to churches like the medieval Riga Cathedral and St. Peter's Church, with a towering steeple. Overlooking the River Daugava, turreted Riga Castle is now the presidential residence, while the ornate red-brick House of the Black Heads exhibits artwork and weapons. Narrow stone streets and broad plazas like Dome Square and Līvu Square are lined with lively restaurants and pubs.
