London School of Hygiene and Tropical Medicine

Founded by Sir Patrick Manson in 1899, the London School of Tropical Medicine moved from the London Docks in 1920, taking up temporary residence around the corner from its current central London location. The school expanded its name following its entry into the Royal Charter in 1924 and opened its existing home in 1926. The private building is rarely accessible, though you can admire the unchanged Portland stone façade at any time, and usually take a tour of the steel-framed, Grade II listed building during London's annual Open House event. If you do have a chance to look around, expect gilded bronze insects and animals decorating the first floor balconies as well as two large open courtyards.
