Fahan House is a beautiful Georgian house built around 1765 on the shores of Lough Swilly. The most famous resident to occupy his house was Agnes Jones (1832-64), the nursing pioneer who spent her early life living here. She trained alongside Florence Nightingale and helped transform the terrible conditions that existed in the Liverpool workhouses during the 1850s and 60s. She is buried in the graveyard nearby. This graveyard was originally an important 6th-century monastery that was established by the O’Neill dynasty who ruled most of Ireland for nearly 600 years from the nearby Grainan of Aileach. Inside the graveyard, you can find the exquisite St Mura’s Cross that dates to the 7th century AD. This is one of the earliest and most beautiful Celtic Crosses in Ireland. It was recorded that this monastery was sacked by Vikings in the 10th century.
