The Oldies tour the oldies.

A perfect blue sky day walking along the Cornish coast, checking out the many disused tin mines (please see extra 1) and prehistoric sites. The main is Ballowall barrow, a late neolithic funerary monument.. In the centre was a mound surrounded by two concentric walls. Contained within were five chambers, containing pottery and possibly graves.
Extra 2: Damselfly, probably.
