LATE EMPIRE WALL
SAINT-SERNIN TOWER
his
is a horseshoe shaped Gallo-Roman tower on the eastern face
of the fortification. The bond
is typical of Late Empire masonry, with alternating rows of
small sandstone blocks and regular layers of brick. The tower
originally had roman
arch windows. The masonry bosses
at the top of these arches clearly attest to the work of the
royal engineers who fortified the ancient curtain
walls with crenellated parapets at the end of the XIIIth
Century.
The tower served as the nave of Saint-Sernin Church which was
built against the rampart in the XIIIth Century and destroyed
during the French Revolution. In the XVth Century a large tracery
window was made in the ancient stonework.
