The Church of Saint Panteleimon is a late Byzantine church in Thessaloniki and a UNESCO World Heritage Site.
The church lies in the eastern part of the old city, near the Tomb of Galerius, at the junction of Iasonidou and Arrianou streets. Its current dedication to Saint Panteleimon was given to the church after the end of Ottoman rule in 1912, and its original dedication is therefore disputed. In Ottoman times, it was converted into a mosque in 1548 and became known as Ishakiye Camii, which in the prevailing scholarly interpretation points to an identification with the late Byzantine Monastery of the Virgin Peribleptos, also known as the Monastery of Kyr Isaac after its founder Jacob, who was the city's metropolitan bishop in 1295–1315 and became a monk with the monastic name of Isaac.
A counter-argument however supports the theory that the present church is unrelated to the Peribleptos Monastery, and that it was converted into a mosque ca. 1500, when the city's kadı (judge), was Ishak Çelebi, whom the mosque was named after. However, the church's architecture and decoration, which date to the late 13th/early 14th centuries, appear to support the former view.
The church is of the tetrastyle cross-in-square type, with a narthex and a (now destroyed) ambulatory that is connected to two chapels (still extant). Very few of the building's original wall paintings survive. Ottoman remains include the base of the demolished minaret and a marble fountain.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
