Built to pursue the rebels
The Military Road
The Military Road - now the R115 - was constructed by the British Army between 1800 and 1809, engineered by Alexander Taylor, with the specific purpose of accessing the Wicklow Mountains after the 1798 rebellion. The mountain terrain had sheltered Michael Dwyer and his men for years; a road through the middle was the answer. It remains Ireland's only surviving purpose-built military road. It passes above Roundwood through the Sally Gap and connects Laragh to the north Dublin mountains.
Dublin's water for 160 years
The Vartry Reservoir
The lower Vartry Reservoir was completed in 1863, championed by Sir John Gray of the Freeman's Journal who pushed through the engineering project that finally gave Dublin a reliable municipal water supply. The upper reservoir was added in 1923. Both still supply Dublin today. The lower reservoir has 7km of walking trails through the surrounding forestry - pine, birch, the occasional red squirrel. The upper reservoir has a 6.4km loop. Between them, they are the quietest walks accessible from the village.
A title that keeps getting contested
The highest village
Roundwood's claim to be Ireland's highest village - 238 metres above sea level - appears in enough guidebooks that the village doesn't question it. Several other Irish villages contest the title, notably Kilronan on Inis Mór and a handful of County Clare settlements. The conversation repeats itself without resolution. Roundwood is undeniably high enough for the weather to come in differently, for the road to ice before the lowland roads, and for the view south across the valley to be worth the altitude.
