Castle upon Alun
Castle Upon Alun is well known in the area for its Ford at Pont-yr-Brown with its stepping stones.
Castle-upon-Alun Farm was once a thatched farmhouse and it may have been the Home Farm of an old castle (hence the name of the area).
Several stone arches and relics of an old building survive and it is thought that a Welsh castle of pre Norman times could have stood in the vicinity. Graves of the first century Roman-Celtic period containing spears and daggers have been unearthed in the area.
