Sarah's Cottage is one of the named corners of the Snaefell Mountain Course used for the Isle of Man TT races. It is situated between the 9th and 10th road side mile-markers at Ballavaish on the primary A3 Castletown to Ramsey Road in the Isle of Man parish of German. A right-turning bend on the course, turning from a north-west direction to the north-east, it precedes Creg Willey's and Lambfell,. A small stone cottage on was occupied by Sarah Corlett of Cronk Dhoo in about 1900. As part of The Long Roundthe journey from Castletown to Ramsey using the primary A3 road made by horse-drawn carriers and later by Charabanc many residents on the route provided food and by the roadside to travellers and the stop at Creg Willey's Hill by Sarah Corlett's cottage was a popular one for refreshments. The many hill-farms in the area also provided passing trade as school children attending the last school on the Isle of Man to still teach Manx Gaelic at the old Cronk-y-Voddy School and they referred to Sarah Corlett in Manx Gaelic as Sarah Vilyn. The cottage is known as Sarah's by the many motorcycle enthusiasts who have used the front garden as a vantage point. The cottage was derelict until 1975 when James Henry Shuttleworth the Lord of Abergwili and his wife Betty, the Lady of Abergwili from Wirral, arrived and totally renovated it and carried on the tradition of selling refreshments to passers by and taking in guests. Betty died in 1988 and Jim carried on living in Sarah's until he died in 2014. The cottage remains in the Shuttleworth family and has been renovated by Roy and Alma Shuttleworth to carry on the tradition. The eponymous cottage is on the outside of the bend, visible ahead as the corner is approached from either direction. When the road is closed for racing, spectators are not allowed on a strip extending past Sarah's Cottage onward, on the outside of the bend. This corner was part of the Highland Course and Four Inch Course used for the Gordon Bennett Trial and Tourist Trophy car races held between 1904 and 1922. Sarah's Cottage was part of the St. John's Short Course used between 1907 and 1910, and the Snaefell Mountain Course used since 1911 for the TT and Manx Grand Prix motorcycle races. During the 1965 TT races, heavy rain and strong cross-winds on the A18 Mountain Roadsection of the course dominated the Senior TT. The notoriously difficult uphill section of the Mountain Course at Sarah's Cottage and the heavy rain and slippery conditions caused Giacomo Agostini to slide-off on lap two. This was followed on lap three when his MV Agusta teammate, Mike Hailwood, crashed at the same spot at Sarah's Cottage. Hailwood bump started his damaged machine, pointing in the wrong direction along the course downhill, turned around and went on to win the race.
