Justinian also had Anthemius and Isidore demolish and replace the original Church of the Holy Apostles and Hagia Irene built by Constantine with new churches under the same dedication. The Justinianic Church of the Holy Apostles was designed in the form of an equal-armed cross with five domes, and ornamented with beautiful mosaics. This church was to remain the burial place of the Emperors from Constantine himself until the 11th century. When the city fell to the Turks in 1453, the church was demolished to make room for the tomb of Mehmet II the Conqueror. Justinian was also concerned with other aspects of the city's built environment, legislating against the abuse of laws prohibiting building within of the sea front, in order to protect the view.
