The origins of the Santa Maria Assunta church are uncertain. Its oldest part is the crypt, built in the 6th century on pre-existing Roman remains. The current church, however, dates back to the 11th century, built by the Norman king Roberto il Guiscardo and consecrated by Bishop Alfano I of Salerno in 1079. The Romanesque construction underwent significant restoration work in the Baroque style during the 18th century (between 1709 and 1716), mainly affecting the interiors.
The facade has a hipped roof with three sloping sides. It features four elements: a Romanesque rose window, a single Renaissance portal with the construction date of the building and the coat of arms of the consecrating bishop carved on its lintel, a marble niche with a bas-relief depicting the Virgin Mary enthroned with the Child and angels, and two stone lions on either side of the portal. The church is flanked by a three-story bell tower, built in the second half of the 12th century. The oldest part is the lower level, where two Roman-era inscriptions (1st century AD) are embedded in the walls, while the other two levels were added in the 15th century.
The interior of the cathedral originally had three aisles until the 18th-century renovations. Today, it consists of a single nave with side altars and the Chapel of the Blessed Sacrament (1627). The presbytery is raised above the crypt below. The wooden ceiling of the nave is adorned with paintings from 1655, with the central depiction of the Assumption of Mary. The dome ceiling of the presbytery is frescoed with a scene from Paradise (18th century), and the pendentives feature representations of the four evangelists. Of notable historical and artistic interest is the Tomb of Giulio Gallotti (15th century). Also worth mentioning are the funerary plaques of the three bishops Giacomo Lancellotto di Tropea, Nicola, and the noble Giacinto Camillo Maradei di Laino.
The crypt, as it appears today, dates back to the time of Roberto il Guiscardo. The vaulted ceiling is supported by fourteen columns made of marble and granite. At the entrance, there is a fresco depicting the Pietà (14th century). The last bishop of Policastro, Federico Pezzullo, is also buried there.
The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
