The Boldog Özséb Lookout Tower stands on the very summit of Pilis (756 m), the highest point of the Pilis mountains and the entire Transdanubian Central Range. Rising over 17 metres, this timber-and-concrete tower offers a full 360-degree panorama from its upper platform, making it one of the most rewarding viewpoints in the region.

What makes this place special is its history - the tower was built by transforming a Cold War-era geodetic survey tower from the 1970s, which for decades stood in a restricted military zone closed to hikers until the 1990s. Today the summit is a peaceful, forested spot, and the surrounding landscape shifts beautifully with the seasons - vivid autumn colours across the Pilis woods, and crisp, far-reaching views in winter. The tower takes its name from Boldog Özséb (Blessed Eusebius), founder of the Pauline order, who according to tradition lived as a hermit in this area.

• Orosdy Castle above Pilisszántó - the shortest route, heading almost directly uphill, quite steep
• Két-bükkfa-nyereg saddle (near the Pest and Komárom-Esztergom county border) - the most comfortable approach, via a marked trail or a paved forestry road closed to public traffic

• Accessible on foot only, via marked hiking trails
• A spiral staircase inside the reinforced concrete core leads up to the viewing terrace
• Nearby you'll find ruins of Pauline and Cistercian monasteries and numerous caves

Interestingly, the area around the tower shelters the largest known Carpathian Basin population of the rare, strictly protected Hungarian ferula (Ferula sadleriana), which survived here largely thanks to the summit's long isolation.
