Museum. After Bonsor's death, his excavation plans and drawings were obtained for the museum. The plans played an important part in the restoration of Bant's Carn in 1970. The Bant's Carn site also includes remains of post-medieval field systems and other settlements. It, together with the nearby late Iron Age/Romano-British village of Halangy Down is now in the guardianship of English Heritage. A military battery built in 1905 also stands nearby.
