Bremen Cathedral of St. Peter (Bremer St. Petri Dom) is the main Protestant church in the city. It is located at the Market Square. Its construction began in the XI century and lasted more than three centuries. Moreover, during the course of work architects had to reconsider the appearance of the building. In point of fact at the beginning of construction the Romanesque style was fashionable, and when the building was built by half, it turned out that the most urgent was the Gothic.
There are regular services in the cathedral, but it is open to visitors. There is also a museum. Bells, which are located inside one of the towers of the cathedral, are considered to be the acoustic symbol of Bremen. The main cathedral bell has a name – Brema – and weighs 7 tons.
Bremen Cathedral is included in UNESCO World Heritage List.
