Bremen's impressive market square sits in the charming Altstadt. It's bordered by the St. Petri Dom, an imposing 900-year-old Gothic cathedral; an ancient Rathaus; a 16th-century guildhall; and a modern glass-and-steel state parliament building, with gabled town houses finishing the panorama. Alongside the northwest corner of the Rathaus is the famous bronze statue of the four Bremen Town Musicians, one atop the other in a sort of pyramid. Their feats are reenacted
in a free, open-air play at the Neptune Fountain near the cathedral, at noon each Sunday, from May to September. Another well-known figure on the square is the stone statue of Roland, a knight in service to Charlemagne, erected in 1404. Three times larger than life, the statue serves as Bremen's good-luck piece and a symbol of freedom and independence. It is said that as long as Roland stands, Bremen will remain a free and independent state.
