Muggia is an Italian town and comune in the extreme south-east of the Province of Trieste in the region of Friuli-Venezia Giulia on the border with Slovenia. Lying on the eastern flank of the Gulf of Trieste in the northern Adriatic Sea, Muggia is the only Italian port town in Istria. The town’s architecture is marked by its Venetian and Austrian history, and its harbour hosts a modern 500-berth marina for yachts (Porto San Rocco). Muggia lies in northern Istria. Its territory, limited on the sea-side by a shoreline of more than 7 kilometres (4 mi) featuring a coastal road and on the border side by a hill system, Monti di Muggia, including Mt. Castellier, Mt. S. Michele, Mt. Zuc and Monte d’Oro, that dominate over a vast landscape of Triestinian and Istrian coast, is characterized by a rich sub-continental vegetation of both Karstic and Istrian type. It has a border crossing, known as San Bartolomeo, with Slovenia and the extreme east of the comune at Lazaretto. The Slovenian border crossing is called Lazaret in the Municipality of Koper.
Among the occurrences characterizing the socio-cultural life of this small city is well worth mentioning the Carnival of Muggia. The Carnival absorbs much of the population of Muggia engaging them in the construction of allegoric carts articulated and moving in order to better mock the chosen victim and in the realization of gorgeous costumes. During those seven days the city becomes a true open-air theatre offering a continuous entertainment that previsibly climaxes in the great parade on the last Sunday. The town also has a museum of modern art named after sculptor Ugo Carà.
Muggia provides many evident traces of its Venetian traditions and origin, as showed by the dialect, the gastronomic traditions, the gothic-venetian style of some houses, the devious “calli”, the loggias, the ogive arches, the ancient coats of arms on the façades but mostly the main square, a true Venetian “campiello”.
Memories of its early ages include an important pre-historic “castelliere” on Mt. Castellier (S. Barbara) and Roman (Archaeological Park of Castrum Muglae) and medieval remains in Muggia Vecchia (Old Muggia), once one of the guarding castles that in the 10th century were built to defend the Istrian border against the invasion of the Hungars. The Castle of Muggia, destroyed in 1353 by the Triestines, retains several remains of the previous period such as the ruins of the walls. A tower dating back to 1374 was due to the Patriarch of Aquileia Marquard of Muggia. Later in 1735, under the government of the Republic of Venice, it was restored, but it was totally abandoned during the following century. The Castle was restored by its current owners, the sculptor Villi Bossi and his wife Gabriella, and may be visited upon request.
The most important art attraction is the little basilica of Santa Maria Assunta (10th-13th century), housing frescoes from the 14th-15th centuries.
