In 1332 the inhabitants of quarter of San Vito moved near the castle of the Counts of Modica, and for this reason a new mother church was built in the same place where the present one is located and it is dedicated to Our Lady of the Assumption. This church opened to worship in 1402, was built in a Catalan-Gothic style with a nave and two side aisles and had a wooden ceiling and side chapels not aligned. It was enlarged and modified in 1471, 1530-1558 and 1581.
Today we can only see the bell tower with double lancet windows (restored in 1942), the chapel of the Holy Thorn and the Baptistery.
The church was rebuilt in 1669 by Giuseppe Diamante and Angelo Italia, while the neo-classical façade was realized in 1786 by Emanuele Cardona.
The garden adjoining the church, since the 15th century, was used as a cemetery for poor people, with an altar where to celebrate Mass during maladies and a stone cross with an aedicula sacred to Our Lady of Mercy. In the 20th century it became a public garden and in 1929 they placed the War Memorial, realized by Bentivegna, a sculptor from Sciacca.
The church has a basilican plan with a nave and two side aisles which are divided by two rows of columns with monolithic marble shafts extracted from the near mount Bonifato. The stuccoes were made by the Curtis, while the floor was realized on the architect Giuseppe Patricolo's plan.
The interior contains 38 frescos by Guglielmo Borremans.
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.
