The Basilica is the largest Franciscan church in the world. Its most notable features are its sixteen chapels, many of them decorated with frescoes by Giotto and his pupils, and its tombs and cenotaphs. Legend says that Santa Croce was founded by St Francis himself. The construction of the current church, to replace an older building, was begun on 12 May 1294, possibly by Arnolfo di Cambio, and paid for by some of the city's wealthiest families. It was consecrated in 1442 by Pope Eugene IV. The building's design reflects the austere approach of the Franciscans. The floorplan is an Egyptian or Tau cross (a symbol of St Francis), 115 metres in length with a nave and two aisles separated by lines of octagonal columns. To the south of the church was a convent, some of whose buildings remain.
