Saint Columba and Portkill Portkill (; probably a shortened version of , meaning 'Colum Cille's port' or 'Colum Cille's landing place') is a small bay just north of Shrove; the bay is located just north-west of Inishowen Head. According to local tradition, Portkill is the point from which
Saint Columba (also known as Colum Cille) left Ireland when he sailed into exile in
Scotland in the mid-sixth-century. Local tradition says that Columba and his followers, having sailed up Lough Foyle from
Derry, landed on the small beach at Portkill in order to take on some drinking water from a spring there. A rock with an ancient inscribed cross upon it is still located beside the small beach at Portkill. Local tradition says that Columba himself cut this cross into the rock using his finger. '
As the crow flies', this is a distance of around 11
miles (slightly over 17.7
kilometres), Portstewart being to the south-east of Shrove. As far as is known, she was only the third woman in history to
swim across the English Channel. Gleitze initially attempted to swim from Portstewart across to Inishowen, making this attempt on 15 August 1929. However, she had to abandon this attempt half-way through, being brought the rest of the way by a motor boat to
Moville on the Inishowen side. Unperturbed by this upset, she decided to try again, this time swimming from Inishowen across to Portstewart. At 3am on the morning of Saturday, 17 August 1929, Gleitze left her lodgings at McConnell's Hotel (now The Foyle Hotel) on The Square in Moville. She was conveyed by motor car to the Pilot's Station at Inishowen Head in Shrove, where, at exactly 4:05am, she entered the water. From Shrove, she swam directly across to Portstewart. This swim took just over eight hours, which she successfully completed, becoming the first known person to complete this feat. She emerged from the sea at Bearnville Port in Portstewart at 12 noon later the same day. Gleitze made the 'return swim' a few days later, on 20 August 1929. On this occasion, she swam from Portstewart to Black Rock Bay, between Moville and
Greencastle. ==References==
