Maria della Piazza, also known in Greek as Panagia or Kerá tou Forou, Panagia of the Market, Santa Maria dei Miracoli, or Madonnina, was a three-aisled timber-roofed basilica situated in the market square, outside the Voltone Gate, between present-day Argyraki and 1821 Streets. It probably served both rites. Following the Ottoman conquest of Candia, it was converted into a covered market (Arasta).

In 1961, when the building was demolished for the construction of a hotel, it was discovered that the masonry piers supporting the roof incorporated marble columns, one of which bore an inscription of the early 11th century naming a Byzantine governor of Crete. This suggests that the basilica was originally erected in the Byzantine period after the reconquest of the island from the Arabs and was subsequently adapted during Venetian rule — as was likely the case with many Byzantine churches in Candia.
