Saint-Sernin at Toulouse, France nave (ca. late 11C)
-barrel-vaulted interior w/ demarcated ribs
-very dark, lacks a clerestory
-double side aisles
-The earliest, truly Romanesque structures are found on the pilgrimage routes in France. This is one such
-features an elongated nave, transept, apse, ambulatory and radiating chapels which give the church the shape of a Latin cross
-The interior view shows a rhythmic, geometric organization of space with the repeating units of barrel vaults above and compound piers below (in architecture, each of these "units" is known as a bay.)
-This "segmented space" is strikingly different from the timber-roofed, flat walled, uninterrupted space of Early Christian basilicas (cf. Sant'Apollinare Nuovo), and is a certain mark of a Romanesque church.
