According to the BBC, the Oak and Feather Grove Druids celebrate summer solstice at what is reported as "Turton Heights stone circle" - I'm guessing this must be what Burl calls Cheetham Close?
From BBC Religion: Local Summer Solstice celebrations
In addition to the large events at major sites such as Stonehenge, many more Pagans hold small ceremonies in open spaces, everywhere from gardens to woodlands.
In this clip the Sunday Programme follows the Oak and Feather Grove, a Druid group whose members come from across Lancashire, as they visit a stone circle at Turton Heights near Bolton to celebrate the Summer Solstice.
