The natural wall of Finestres, La Franja.
These rocks are called Roques de la Vila ("the town's rocks") but many people call them "The Great Wall of Finestres". The eroded limestone is a completely natural occurrence, but it looks like a human-made or even giant-made wall. Taking advantage of it, Medieval inhabitants of the area built a little castle and a chapel dedicated to Saint Vincent between the two "walls".
