Ajdovščina: Roman Walls, Hiking Trails and Culture

A nearly continuous Roman fortification wall with fourteen towers defines the Castra site in Ajdovščina. There is also a Roman fort, art and culture, and trails along the edge of the Gora Plateau. You can tailor your stay to different interests: history and exhibitions, hiking and cycling, or unusual rock formations and landscape views.

Roman Traces and Art

In Ajdovščina, Castra preserves an impressive Roman fortification wall. The experience “Secrets of the Roman Fortress Castra,” announced in April 2026, is intended to bring the walls, towers, baths and remains of an underfloor heating system to life. It is intended to combine history, storytelling and interactive elements. Visitors are expected to be able to explore the fortress independently or join a guided tour; check whether the experience is available before your trip.

Near Hrušica, the Roman fort Ad Pirum stands at an elevation of 858 metres on the Roman road between Aquileia (Oglej) and Emona (Ljubljana). The Archaeological Park can be visited independently at any time; nevertheless, check the visiting conditions before you go. The park also includes a small exhibition at the Stara pošta inn in Hrušica. Those interested in the region’s heritage can find around 1,200 fossils from across Slovenia in the Ajdovščina museum collection.

Art and sacred history offer further reasons to visit. The Pilon Gallery permanently displays paintings, drawings, prints and sculptures by Veno Pilon, and hosts temporary exhibitions of fine art, design, architecture and photography. The Church of St John the Baptist in Ajdovščina preserves 18th-century frescoes and a Stations of the Cross by Anton Cebej. At Tabor nad Črničami, the northeastern of the former two defensive towers and the northern of the two fortified entrances still remain.

Hiking, Cycling and Rock Formations

Predmeja is a starting point for hiking and cycling trips. The Pot po robu hiking trail runs from Predmeja to Col along the edge of the Gora Plateau. Along the way, views open up over the Vipava Valley, the Karst, and the Gulfs of Trieste and Piran. There is a large gravel parking area at the starting point by the Materi Gorjanki monument. Check the parking conditions before setting out.

Among the area’s unusual natural features is Bošnarjevo brezno at Predmeja. It is considered the cave there that is easiest for visitors to access and has three entrances and a natural bridge over a wide chasm. Conditions for entering the underground may vary. Otliško okno is another natural bridge: the rock opening is twelve metres high and seven metres wide at its widest point. Its formation is linked to a major tectonic fault, as well as to the weathering and erosion of the rock.

At Hubelj, after several days of rain, a large volume of water emerges from underground through three caves: Veliko Hubeljsko kuhinjo, Pajkovo mrežo and Vzhodno Hubeljsko jamo. Those interested in the forces that shape rock and water will find a different side of nature here from the scenic Pot po robu trail. The Kovk take-off site for paragliding is 860 metres above sea level.

Culture and Food and Drink in Vipavski Križ

Vipavski Križ is a historic cultural site in Slovenia, surrounded by town walls. The Capuchin monastery houses a library with numerous manuscripts, unique book editions and outstanding works of art. Visitors can tour the monastery by prior arrangement. The renovated wine cellar in the castle hosts numerous cultural and social events. For wine tastings, Vinoteka Vipavski Križ in the Grajska klet offers guided sessions by prior arrangement.

Another culinary stop is the independent microbrewery Pivovarna Pelicon. It brews unfiltered and unpasteurised beers, which visitors can buy and taste in its own shop. As visitor offerings may change, it is advisable to check the options before your visit.

Plan Your Visits

The activities differ in how much planning they require: Ad Pirum can be visited independently, while visiting the Capuchin monastery and wine tastings in Vipavski Križ require advance notice or an appointment. Check availability for the “Secrets of the Roman Fortress Castra” experience. The Rally Vipavska dolina is also best planned around the specific dates: it takes place in the Ajdovščina and Vipava area and includes a night-time super special stage in the centre of Ajdovščina; dates and programme vary.
