Sopeira is a small village in the
Ribagorza region. From Pont de Suert drive south on the main road towards Lerida.
You'll drive along the lake and soon find Sopeira with its Monastery de Alaón.
There is plenty of parking space at the monastery.
At the time of the pictures the stones were in front of the monastery.
They have been moved since then and they are now between the walls. The coordinates reflect this.
