Higher water levels and floods also eroded the islands’ embankments which at the time were made of wood and the latter also damaged the buildings, which were also wooden. In Orti di Ammiana the monastery of Santa Cristina was given funds for major repairs in 1332 and 1343 and the Santi Apostoli Filippo e Giacomo was also given funds for the same purpose in 1343. The monastery of Santa Maria Maddalena in the Tumba Gaiada was also given a grant for repairs in 1371. The churches in Costanziaco, which was along the channel formed by the Sile was adversely affected earlier. The San Pietro church and the Santi Sergio e Bacco parish church (founded in the 11th c.) were given to the Sant’Adriano monastery in 1271. The other parish church, Santi Massimo e Marcelliano (11th c.) was already abandoned in 1279. San Matteo (1229) was abandoned in 1298, San Mauro (12th c.) in the 13th c. Santi Giovanni e Paolo (1228) lasted until 1400. The monastery of Sant’Adriano (1160) was abandoned in 1526, outlasting the churches and monasteries of Ammiana. This was probably because the island it was on, Sant’Ariano, had more elevated ground than all the other nearby islands. Lio Piccolo was also affected. Its church of San Salvador (1183) was abandoned in 1301. In the island group of Ammiana, Sant’Apostoli Filippo e Giacomo (Orti di Ammiana, founded in 1185) was abandoned in 1387, San Felice e Fortunato (Tumba Leseda, 1074) in 1419, Santa Maria de Galiada (Tumba Gaiada, 1231) in 1415, San Marco/Santa Cristina (Orti di Ammiana, 1185) in 1432, San Lorenzo (Castrazio, 10th c.) in 1438, Sant’Angelo (Orti di Ammiana, 1195) in 1438, Santi Andrea e Giacomo (Ammianella, 1152) in 1455. Sometime after the abandonment of Ammiana and Constanziaco, some of their islands were submerged by the waters of the lagoon and have disappeared.
