Perquage

The perquages are a series of routes in Jersey, Channel Islands. Some claim the routes that offered sanctuary to malefactors to leave the island. All except St Ouen and St Martin lead to the south coast. For example, St Mary, St John and St Lawrence leave via St Peter's Valley and Beaumont.
The full list of the perquages are:

St. Clement
St. Catherine's Valley
Grève de Lecq Valley
Le Marais du Val
Les Vaux
Saint Peter's Valley
Les Grands Vaux / La Vallée des Vaux

Use

In Caesarea, Jean Poingdestre states the perquages were 24-feet wide highways beginning at the parish churches and leading to the sea. The only known use of them was the conduct of those who had taken sanctuary. However, elsewhere he considers that to be false. Instead he considers that the roads were for public use such as army manoeuvres.
