St. Maria Lyskirchen is the smallest of the twelve Romanesque churches in Cologne. It was founded in 948, and the present building dates from 1210-1220, with some later additions in the Gothic style. The upper parts of the west front were rebuilt in the 19th century. The church is in the form of a three-aisled basilica, with a chancel flanked by two towers, only one of which was constructed to its full height, and an eastern apse. The building received only minor damage during the wars.
The church has a sculptured Romanesque portal, and a cycle of 13th century ceiling paintings. Rediscovered in the 19th century, they are unique in Cologne and show stories from the Old and New Testaments. The church contains the 'Schiffermadonna' (Seaman's Madonna), a wooden statue of 1420. A triptych by Joos van Cleve, with a central panel of the Lamentation, was sold in 1812; a few years later it was replaced with a copy by Benedikt Beckenkamp, which remains in the church.References:
The Temple of Portunus or Temple of Fortuna Virilis ('manly fortune') is one of the best preserved of all Roman temples. Its dedication remains unclear, as ancient sources mention several temples in this area of Rome, without saying enough to make it clear which this is.
The temple was originally built in the third or fourth century BC but was rebuilt between 120-80 BC, the rectangular building consists of a tetrastyle portico and cella, raised on a high podium reached by a flight of steps, which it retains.
The temple owes its state of preservation to its being converted for use as a church in 872 and rededicated to Santa Maria Egyziaca (Saint Mary of Egypt). Its Ionic order has been much admired, drawn and engraved and copied since the 16th century. The original coating of stucco over its tufa and travertine construction has been lost.
