Diocletian's Palace (Dioklecijanova palaca in Croatian) is a building in Split in Croatia that was built by the emperor Diocletian at the turn of the fourth century AD. The Latin name of the city, Spalatum, was drawn from that of the nearby Greek colony Aspalathos, which in turn was named after a white thorn common in the area. Contrary to popular belief, it has nothing to do with the Latin word for palace, palatium.

Circular and polygonal plans appear in a number of Syrian examples of the early sixth century. Their most striking feature is the inscribing of the circle of polygon in a square which forms the exterior outline, and the use of four niches to fill out the corners. This occurs at Kelat Seman, a small double church, perhaps the tomb and chapel of a martyr; in the cathedral at Bozrah, and in the small domical church of St. George at Ezra. These were probably the prototypes of many Byzantine churches like St. Sergius at Constantinople, and San Vitale at Ravenna.

"It was in Central France, and mainly along the Loire, that the systematic development of vaulted church architecture began. Naves covered with barrel-vaults, sometimes of pointed section, appear in a number of large churches built during the eleventh and twelfth centuries, with apsidal and transeptal chapels and aisles carried around the apse, as in the imposing church of St. Sernin at Toulouse, in Provence. The thrust of these ponderous vaults was clumsily resisted by half-barrel vaults over the side aisles, transmitting the strain to massive side-walls."

The Cathedral Church of Christ, Blessed Mary the Virgin and St. Cuthbert of Durham, commonly referred to as Durham Cathedral, in the city of Durham, England, was founded in AD 1093 and remains a center for Christian worship today. It is generally regarded as one of the finest examples of a Norman cathedral and has been designated a UNESCO World Heritage Site along with nearby Durham Castle, which faces it across Palace Green, high above the River Wear.
