ESB Liffey scheme, late 1930s-1940s
The valley they flooded
The Poulaphouca Reservoir is a working piece of infrastructure, not a natural lake. The Electricity Supply Board dammed the River Liffey and the King's River at Poulaphouca between the late 1930s and the early 1940s to generate hydroelectric power and to supply water to the growing city of Dublin. The water rose over the floor of the valley and stayed there. The townland of Ballinahown, northeast of the village, went under completely; other townlands lost their best low ground. Families were moved and farms were broken up. Valleymount survived because it sat on higher ground, and that is why it now looks out over water on three sides. On a still day the reservoir is beautiful. It is worth remembering it is also a grave for a whole valley's worth of fields.

St Joseph's and the Harry Clarke windows
St Joseph's Catholic Church was built in 1803, with a curved porch added around 1835 that gives the building its unusual, almost Mexican silhouette - a look local tradition puts down to ideas carried home by emigrants who had spent time in New Mexico. The real treasure is the glass. In 1924 a stained-glass window of St Therese of Lisieux, the Little Flower, was commissioned from Harry Clarke, the greatest Irish stained-glass artist of his generation. Eleven years later three more windows were ordered from Harry Clarke Stained Glass Ltd - the Sacred Heart, Our Lady, and St Anthony of Padua. Four Clarke windows in a tiny west-Wicklow village church is the kind of thing that brings art students out from Dublin on a fine afternoon. The church is usually open; go in and look up.

Braveheart drive and the film valley
The drowned valley and the open hills around Poulaphouca have pulled in film crews for decades. Mel Gibson shot scenes for Braveheart here in 1995, and a stretch of the lakeside road is still locally known as the Braveheart Drive. The valley also turns up in This Is My Father (1998), Widows' Peak (1994) and P.S. I Love You (2007). None of it makes Valleymount a film town, but if the landscape on the drive in feels strangely cinematic, there is a reason.
