Ajdovà ¡ÃÂina (; , ) is a town in the Vipava Valley (Vipavska dolina), Slovenia. It is the administrative seat of the Municipality of Ajdovà ¡ÃÂina.
The first mentions of Ajdovà ¡ÃÂina go back to circa 2000 BC. In the Bronze Age and the Iron Age a fortified settlement stood on the nearby hill of Gradià ¡ÃÂe. In the early period of the Roman Empire, after a road was built from Aquileia towards Emona, a small post and goods station known as mansio Fluvio Frigido stood on the site of today's Ajdovà ¡ÃÂina.
In the late 3rd century and the early 4th century a fortification system, Claustra Alpium Iuliarum, which run from the Kvarner Gulf to Cividale, was built by the Roman Empire. Its centre was the fortress of Castra or Castrum ad Fluvio Frigido, the remains of which are today still visible in Ajdovà ¡ÃÂina.
Despite the fact that the Italian border is less than 20 km away and that Ajdovà ¡ÃÂina was under Italian administration from 1918 to 1947, and from 1927 as a commune of the Province of Gorizia (as Aidussina), during Italian rule (1918âÂÂ1943, nominally lasted to 1947), the style of the town does not resemble that of a typical Italian town. The strong bora winds would cause damage to the usual Italian house construction. Thus the population adopted and modified the classical Karst architecture for their own needs; for example, by putting stones on roofs to weight down the tiles against the strong winds.
After World War II Ajdovà ¡ÃÂina became the economic and cultural centre of the upper Vipava Valley. Major industries include textile fabrics, construction, food, beverages, and furniture.
Ajdovà ¡ÃÂina annexed the formerly independent settlements of Gradià ¡ÃÂe and à  turje () in 1953.
The Hubelj River is the dividing line between the two largest parts of Ajdovà ¡ÃÂina, locally known as à  turje and Ajdovà ¡ÃÂina. During the pre-World War I years the river was also the border between the Austrian lands of Gorizia and Gradisca and Carniola.
The climate is Mediterranean (minimum temperature in winter , maximum ; in the summer time maximum temperature , minimum . The town is located around 25 km from the Adriatic Sea.
The parish church in Ajdovà ¡ÃÂina is dedicated to John the Baptist and belongs to the Diocese of Koper. It is built on the site of a Roman cemetery. Its interior was painted by the local Baroque painter Anton ÃÂebej. A second parish within the urban area of Ajdovà ¡ÃÂina is the Parish of à  turje, with the parish church dedicated to Saint George and another church dedicated to Saint Lawrence. The church in the hamlet of Fuà ¾ine north of the main town, dedicated to Saint Anthony of Padua, also belongs to this parish.
