Loretto School, founded in 1827, is an independent boarding and day school for boys and girls aged 0 to 18. The campus occupies 85 acres (34 ha) in Musselburgh, East Lothian. It has approximately 600 pupils.
The school was founded by the Reverend Thomas Langhorne in 1827. Langhorne came from Crosby Ravensworth in Westmorland. He named the school for Loretto House, his then home, which was itself named for a medieval chapel dedicated to Our Lady of Loreto which had formerly stood on the site of the school. The school was later taken over by his son, also Thomas Langhorne. The last link with the Langhorne family was Thomas' son John, who was a master at Loretto from 1890 to 1897, and later headmaster at John Watson's Institution. Loretto was later under the headmastership of Dr Hely Hutchinson Almond from 1862 to 1903.
Loretto's campus includes an Indoor Golf Centre, Pinkie House as well as a 300-seat theatre and 600 seat Chapel. The school is made up of three parts – the Nursery for children aged 0–5, the Junior School ('The Nippers') for children aged 5 – 12 and the Senior School for those aged 12 and over. Pupils attend as boarders, flexi-boarders and day pupils and are all attached to a specific house. Houses include Schoolhouse (for day pupils), Seton house (for 2nd to 5th form boarder boys), Holm house (for 2nd to 5th form girls), Balcarres house (for 6th form girls), Eleanora Almond house (for 6th form girls), Pinkie (for 6th form boys) and Hope house (for 6th form boys).
