The Castel (labelled Castellas hereabouts) Roc is the remains of a XIIth century castle and home to Notre Dame du Roc; all completely restored.
The old entrance of the town her is labelled “Portal blanc” (White Gate). The Tour l'Horloge (clock tower) dates from the 14th or 15th century and was a defensive work of the old ramparts of the city. It is flanked by the stand out bell tower, rebuilt in 1730.
Only 20 minutes from Millau (or 40 from Montpellier), this place is worth a look when you're going past. You could include it in your day itinerary to La Couvertoirade or Roquefort as a suggestion.
It's obviously a go-ahead place and access to the A75 ensures its vitality.
You can clearly see that this is a town on the make by these pictures. Clean streets, quality restoration and that imaginative sculpture all add up to a place that deserves more time than I (or any other VTer apparently) gave it.
This place really hums in summer with flea markets in July/August, a 10 day Castel Roc Festival in August and a mountain bike race in September, there are activities here to attract your attention almost as much as that eye catching sculpture that seems to reflect life and nature throughout the history of Le Caylar. The roof over the sculpture was added in 1992.
