The Bremen Cathedral, which is dedicated to St. Peter, has a long and dynamic history. The cathedral is part of the Bremian Evangelical Church, thus making it the proto-cathedral for the last Prince-Archbishopric of Bremen. Its original building is thought to have been a timber-framed church built in the 8th century. The Cathedral has been built and destroyed several times since then; the current building boasts impressive twin towers built in the 13th century which raise high above Market Square where it is situated. Inside there are ancient hand-carved choir stalls and five different organs which are carefully used and maintained. There are also two crypts containing the mummified bodies of around 90 archbishops and other church leaders. Come for a congregation or for one of the public concerts offered by the church.

The very first culture church in the city, Kulturkirche Saint Stephani has been on the listed monuments list since 1973. The church conducts regular services, but apart from that, it focuses on promoting cultural activities. Reading, lectures, and discussions take place at the church quite often. It also plays host to musical concerts. Many exhibitions are held at the church. Local festivals and theatrical performances can be attended at the church as well. During events, the church is open from 11 am to 5 pm from Tuesday to Sunday.

Founded in 1229, St Martin's Church is one of Bremen's major landmarks of the city. This protestant church is open to public and is still a practicing religious organization. Mass is held every Sunday at 10a along with Sunday School. The Gothic structure offers a marvelous display of architecture and art. Notice the stained-glass windows covered in elaborate biblical scenes, the magnificent carved pulpit and the monumental Baroque Organ. The church's clock tower or glockenspiel rings out "Praise to the Lord" composed by Joachim Neander every hour and is a captivating sound that can be heard for miles.

Kirche Unser Lieben Frauen, which falls under the protestant Bermische Evangelische Kirche, has a history of nearly a 1,000 years. Perhaps the oldest church in Bremen, this architectural marvel is flanked by a Romanesque tower on its southern side, with its basement adorned with medieval frescoes, and the church has had few major changes done to it in the course of its existence.
