The Main Building is the oldest structure in the University of Hong Kong.
It was a gift from Sir Hormusjee Navrojee Mody and was designed by Alfred Bryer of Messrs Leigh & Orange. Construction began in 1910 and was completed in 1912.
The building, composed in the beginning of two courtyards with plam trees now over thirty feet high, was conceived in the Post-Renaissance Style which employed giant (2-storeyed) Ionic orders and Serliana windows in the then prevalent red brick and granite construction.
