Basilica of the Holy Apostles, Cologne

The Basilica of the Holy Apostles is a Romanesque church in Cologne (Köln), located near Innenstadt's busy Neumarkt (Köln). It is one of the Twelve Romanesque churches of Cologne from that period. It is historically proven that a monastery was founded here in the 10th century. Its historically secured first Apostle Church was probably a relatively simple building. The former collegiate church is dedicated to the twelve Apostles. Either under Archbishop Heribert, who ruled from 999 to 1021, or subsequently under Archbishop Pilgrim (reign 1021–1036), a large new Salian building was built. Of it are still preserved: large parts of the outer walls of the nave, the western transept and parts of the central nave walls. However, the thin outer skin, the visible wall of these walls, was renewed several times, so that only the core area of these walls still dates from the 11th century.
