St. Andrew's is a 10th-century Romanesque church located in the old town of Cologne. It is one of twelve churches built in Cologne in that period. Archbishop Gero consecrated the church in 974, dedicating it to St. Andrew, although an earlier church at the site was dedicated to St. Matthew. In the 12th century, the church was rebuilt in the Romanesque style, and was probably completed after the great fire of Cologne in 1220.
In the crypt of the church lies a Roman sarcophagus from the 3rd century, which holds the remains of the 13th-century theologian and natural philosopher St. Albertus Magnus. Since 1947, the Dominican Order has ministered to 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.
