[1][2] Following a fire in 1949, a Lathallan student's parent, Charles Alexander, allowed the school to use Brotherton Castle premises at Johnshaven, Montrose, Angus.

[11] He had introduced the Nuffield Science syllabus at Lathallan,[12] with inquiry-based discovery learning in the traditional subjects of physics, chemistry and biology.

[14] When nine-week old Oxford Sandy and Black piglets arrived at the school in 2018, they added to the farm environs that also included "...a treehouse classroom, zipwire, polytunnel, potato field and chickens".

[18] The band was officially established in 1964 and until 1972 it was led by Harry Stott, who had learned to play bagpipes with the King's Own Scottish Borderers in World War I.

[18] In 2009, the band published the CD Blaw na Gael and the cut "Highland Cathedral" (the Lathallan school song) was voted "Castaway's Favourite" on BBC Radio 4 Desert Island Discs in 2015.

[22] The Lathallan pipe band program received a £1000 donation from the Montrose Port Authority after their performance at the 2019 opening of its North Quay.
