Mount Pleasant is an 18th-century mansion situated on Sharrow Lane in the Highfield area of the City of Sheffield in South Yorkshire, England.
[3] The house was constructed in 1777 using the architect John Platt (1728–1810) of Rotherham, who was also involved in masonry work at Clifton Hall and Wentworth Castle during his career.
[4] When first built the mansion stood in a rural situation within sight of the centre of Sheffield, surrounded by farmland at the top of a slight gradient overlooking the valley of the River Sheaf.
In 1868 the committee of the West Riding County Asylum at Wakefield acquired a five-year lease on Mount Pleasant and used it to alleviate overcrowding at their main hospital.
[6] In 1874 Mount Pleasant became the Girls’ Charity School when it was relocated from its original location in St James Row at the side of Sheffield Cathedral.
