In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines.

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.

"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."
