Hill of Allen

Hill of Allen is a volcanic summit in County Kildare that rises approximately 206 meters above sea level. It sits at the eastern edge of the extensive bogland landscape known as the Bog of Allen.

The summit played a key role in early Irish history when the Battle of Allen took place in 722 AD between Leinster forces and the armies of Fergal mac Máele Dúin. This conflict established the site as an important historical location.

In Irish mythology, this summit served as the fortress of Fionn mac Cumhaill, the leader of the legendary Fianna warriors. This ancient story continues to shape how locals and visitors understand the place today.

The summit is partially affected by quarrying operations conducted under a long-term agreement. Visitors should be aware of this when planning a visit and check current conditions at the site.

A circular stone tower built at the summit in 1863 carries the carved names of the workers on its steps. This structure is a rare example of how ordinary laborers were memorialized through their work.
