The most important attraction of Monte Sant'Angelo is the
Sanctuary of Saint Michael the Archangel, built in the 13th century by
Charles I of Anjou. On June 25, 2011, the World Heritage Committee added the Sanctuary of San Michele Arcangelo in Monte Sant'Angelo to the UNESCO World Heritage List. The Sanctuary is one of the seven groups of historic buildings included in the World Heritage Site "
Longobards in Italy. Places of the power (568-774 A.D.)". Other sights in Monte Sant'Angelo include: • The Castle, with bastions of different ages. The most ancient part, called
Torre dei Giganti ("Giants' Tower") is a pentagonal tower high, with walls thick. Its first recorded historical mention dates to 979. Later it was the residence of
Rainulf I of Aversa and the
Robert Guiscard, who built the Norman Tower and the Treasure Hall. Emperor
Frederick II restored the construction to use it as residence for his mistress
Bianca Lancia, while under the
Angevins it was used mainly as prison. Later, from 1464 to 1485, the fortress was the residence of the exiled Albanian condottiero
Skanderbeg. The castle was largely rebuilt in the late 15th century by
Ferdinand I. According to legend, the castle is home to the ghost of Bianca Lancia (popularly known as "Biancalancia"), whose sighs can be heard especially in the winter. • The Tomb of
Rothari (Baptistry of San Giovanni in Tumba), a baptistery dating from the 12th century accessible from the 18th century church of St. Peter. The portal has notable reliefs depicting biblical events. • The church of
Santa Maria Maggiore (11th and 12th centuries). The façade has blind arcades and a baldachin portal with sculpted frames. The interior has a nave and two aisles, divided by columns with sculpted capitals. The walls have Byzantine-style frescoes. •
Pulsano Abbey, at from the city. It was built in 591 over a Pagan temple and was largely destroyed by an earthquake in 1646. ==Economy==
