Ligny Tower is a coastal watchtower built between 1671 and 1672 at a strategic position on the city's western coast. Today, the tower is in good condition, and it is open to the public as an archaeological museum.
Ligny Tower was built on a narrow strip of land on Trapani's western coast, to defend the city from attacks by the Barbary corsairs. It was named after the Viceroy of Sicily, Claude Lamoral, 3rd Prince of Ligne, who had ordered its construction. The tower was designed by the Flemish architect Carlos de Grunenbergh. It has a square base with scarped walls, with four corner turrets which originally contained lanterns.
A passage connecting the tower with the mainland was built in 1806, and guns were installed on the tower's roof until 1862. It was subsequently used as a semaphore station, but it was eventually abandoned.
In World War II, the tower was used by the Regia Marina and was armed with anti-aircraft guns.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
