Considering the Europa Ancona in Ancona?
A VT member wrote the following comment about visiting Ancona:
Santa Maria della Piazza by Airpunk
This church, built in the 11th century, was built on the ruins of two early christian churches from the 4th and 5th century. Floor mosaics from these old churches can still be seen there, but now, they are hanging on a wall. The façade is said to be very beautiful, but ? as often ? I just saw that it is being refurbished. The church once had several other names, including Santa Maria del Canneto and Santa Maria del Mercato.
