In Venice, the second and current St. Mark's Basilica was built on the site of the first between 1063 and 1072, replacing the earlier church while replicating its Greek cross plan. Five domes vault the interior (one each over the four arms of the cross and one in the center). These domes were built in the Byzantine style, in imitation of the now lost Church of the Holy Apostles in Constantinople. Mounted over pendentives, each dome has a ring of windows at its base. These five windowed domes reflect the addition of windows (within tall drums) in the remodeled Byzantine original. However, the tall outer shells at St. Mark's were not added until after 1204. The later high wooden outer domes with lead roofing and cupolas were added to St. Mark's Basilica between 1210 and 1270, allowing the church to be seen from a great distance. In addition to allowing for a more imposing exterior, building two distinct shells in a dome improved weather protection. It was a rare practice before the 11th century. The fluted and onion-shaped cupolas of the domes may have been added in the mid-fifteenth century to complement the ogee arches added to the facade in the late Gothic period. Their shape may have been influenced by the open and domed wooden pavilions of Persia or by other eastern models. Initially, only the center dome had one.
