Bazas Cathedral was the seat of the Bishop of Bazas until the French Revolution (after which it was not restored but was instead, by the Concordat of 1801, divided between the dioceses of Bordeaux, Agen and Aire) and its main attraction is still the cathedral dedicated to Saint John the Baptist, so named because the blood of John the Baptist was venerated here. The cathedral dominates the town and stands at the east end of a wide, open space called the parvis.
The cathedral dates mainly from the 13th-14th centuries, and was built on the model of the great Gothic cathedrals of northern France. The west front is unique with its three noticeable levels: the first includes the three Gothic portals retaining part of their original 13th-century sculpture; the second includes the rose window from 1537; and the third is a Neoclassical gable from 1723. The belfry on the north is part 11th century up to the openings.
The interior consists of a long, narrow nave, with no transept, and was entirely rebuilt from 1583-1635 after the Huguenots badly damaged it in 1561 during the Wars of Religion.
The cathedral is part of the World Heritage Sites of the Routes of Santiago de Compostela in France.
References:Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure.
