The Panagia Ekatondapyliani , which dates from AD 326, is one of the most splendid churches in the Cyclades. The building is three distinct churches: Agios Nikolaos, the largest, with superb columns of Parian marble and a carved iconostasis, is in the east of the compound; the others are the Church of Our Lady and the Baptistery. The name translates as Our Lady of the Hundred Gates, but this is a wishful rounding-up of a still-impressive number of doorways.
