Basilica of St. Francis of Assisi
The Basilica of St. Francis of Assisi is divided into two parts: one is known as the "lower church", built in the rock on one side of Mount Subiaso between 1228 and 1230, and the other as the "upper church", built above it between 1230 and 1253, in the Gothic style. The bell tower is in Romanesque style. The two churches, united under the same name of "basilica", have been listed as UNESCO World Heritage Sites since 2000. The body of St. Francis was secretly transferred to the crypt in 1230 and was so well hidden that it was only rediscovered in 1818.
