Trinitatiskirche

One of the oldest houses in Cologne, built between 1220 and 1225, with an impressive Romanesque façade. Built as a residence for a local patrician, today it houses the Academy of Media Arts.

St. Maria in Lyskirchen is the smallest of Cologne’s twelve Romanesque churches, famous for its remarkably well-preserved 13th-century ceiling frescoes, the only ones of their kind to survive largely intact in the city. Located near the Rhine, it has long been the traditional church of the river boatmen and houses the beautiful "Schiffermadonna" (Boatmen's Madonna), a late Gothic wooden statue from around 1420.

One of the best-hidden gems of Cologne, the small yet ornate gothic gate once led to an "immunity" belonging to the convent based at the St. Maria im Kapitol.

The oldest and largest of Cologne's Romanesque churches, built upon the foundations of a Roman temple. Its unique floor plan is modeled after the Church of the Nativity in Bethlehem and houses treasures such as an 11th-century carved wooden door and a 14th-century crucifix. Sightseeing is limited to times outside of religious services.
