The northern apse is visible to the left, beyond the tower. The transept of the nave closes behind the West Tower. [Dupe of 3415]\u000a\u000aDominated by the cathedral, the city changed its appearance from the 10th century with the construction of St Maria im Kapitol, Gross St Martin (1150-1230), St C\u00E4cilien (ca. 1130-1160; now part of Schn\u00FCtgen-Mus) and St Aposteln (begun ca. 1030), which rose above the tightly packed burgher houses. One of the twelve Romanesque-era churches left in Cologne, which formed the shape of a cross within a circle in the city. Sancta Colonia was thus laid out according to the Christian plan of redemption by Archbishop Bruno I (953-965). St Aposteln is a three-aisled basilica with three apses (triconch choir, ca. 1200) and a small octagonal tower at the crossing.
