Budva is a Montenegrin town on the Adriatic Sea, former bishopric and present Latin Catholic titular see. It has around 14,000 inhabitants, and it is the centre of Budva Municipality. The coastal area around Budva, called the Budva riviera, is the center of Montenegrin tourism, known for its well-preserved medieval walled city, sandy beaches and diverse nightlife. Budva is 2,500 years old, which makes it one of the oldest settlements on the Adriatic coast.

The Old Town of Budva is situated on a rocky peninsula, on the southern end of Budva field. Archaeological evidence suggests that Illyrian settlement was formed on the site of the Old Town before Greek colonization of the Adriatic. While the site was permanently settled since Roman era, most of existing city walls and buildings were erected during the Venetian rule.

The entire town is encircled with defensive stone walls. The fortifications of Budva are typical of the Medieval walled cities of the Adriatic, complete with towers, embrasures, fortified city gates and a citadel.

Originally, there were gates on all of the four sides of the walled city. However, sea-facing gates were closed up over the years. The main city gate is Porta di Terra Ferma, the grand entry to the city from the west. It is also the beginning of the city's main thoroughfare, Njegoševa Street. There are also four more gates on the north wall, facing Budva marina (Porta Pizana, Porta Pizana 1 and 2, and Porta Pizanella), and one small gate facing the southwestern beach of Ričardova glava.

The layout of the town is roughly orthogonal, although many streets deviate from the grid, resulting in somewhat irregular pattern, with many piazzas connected with narrow streets. Today, the entire city within the walls is pedestrian-only.

The town citadel is situated on the southern tip of the city. Originally known as Castle of St Mary, fortification was continually rebuilt and expanded through Middle Ages, reaching its final form during the Austro-Hungarian rule. The sea-facing 160m long ramparts of the citadel, complete with eastern and western towers, are intricately connected to the rest of the city walls. Austrian stone barracks form the most prominent structure within the castle, separating the citadel from the rest of the walled city. Ruins of the Santa Maria de Castello church, after which the entire complex was originally named, are located within the citadel.

A large public square is located to the north of the citadel, containing all of the churches of the old town - St. Ivan church (17th century), Santa Maria in Punta (840 AD), and The Holy Trinity church (1804).
