Maen Llia
Mae Maen Llia wedi gwarchod Heol Senni i'r gogledd o Ystradfellte ers dyddiau Neolithig. Saif dros 12 troedfedd ac mae'n amlwg o Fan Nedd ac o Fan Llia.
North of Ystradfellte, in the Brecon Beacons National Park, along Heol Senni extends a broad valley flanked by Fan Nedd to the west and Fan Llia to the east. the old Roman road - Sarn Helen runs along much of the valley and this huge standing stone has been an iconic marker for thousands of years. It's 12ft high and 9ftwide but a mere 2ft thick.
