Immediately above Bon-y-maen on the top of Kilvey Hill is the main TV transmitter for Swansea. The local rugby team is Bonymaen RFC. Bonymaen is a Communities First area. Bôn-y-maen is Welsh for 'Base of the stone' and there are legends that the same stone ends in Penmaen (English: Stone End) on the Gower Peninsula.
