The small village of La Herlière in Pas de Calais has an unusual two-level chalk quarry near the church, In World War II it was used by British Forces and several inscriptions and carvings date from this period. The carvings include a large lion’s head which give the quarry its nickname.
Access today is via a descending curving staircase, probably dating from the WWI period. Much of the original spoil appears to have been kept within the quarry and used to elevate the floor level. The map shows an approximate location to protect the privacy of the land owner.
