Campus of Chulalongkorn University

The campus of Chulalongkorn University in Bangkok occupies an area of 637 rai (101.9 ha; 252 acres) in the city centre's Pathum Wan District.

The campus sits on what was originally royal land surrounding Windsor Palace, granted for the university's use at its foundation in 1917 by King Vajiravudh.

It was followed in the next three decades by several historic buildings, mostly designed by Phra Sarotrattananimman and showing increasing modern influence, reflecting the country's transition to constitutional monarchy.

The campus is bisected by Phaya Thai Road, with most of the faculties located on the east side and supporting facilities, residences and administration offices on the west.

The land now occupied by Chulalongkorn University had been cleared for paddy fields around the mid-19th century, and part of it had been claimed by Somdet Chaophraya Borommahaphichaiyat, a high-ranking noble under King Mongkut (Rama IV, r. 1851–1868).

New administrative buildings were built on the west side in 1941, while Windsor Palace had been demolished for the construction of Supachalasai Stadium (on land leased to the Department of Physical Education) in 1935.

Together with Uthenthawai School of Construction, they occupy a block that splits the east part of the university campus into separate areas.

In the middle of this area are the Sala Phra Kieo multi-purpose hall and Chula Chakrabongse Building, which houses the student clubs and government.

The faculties of Education (including Chulalongkorn University Demonstration School), Law, and Communication Arts occupy the southern end of the campus's west side, while administrative offices, academic and sporting facilities, student dormitories, and other institutes take up most of the rest.

East of Henri Dunant Road, the Faculty of Medicine shares its campus with King Chulalongkorn Memorial Hospital of the Thai Red Cross Society.

The university campus is dominated by the Auditorium, in front of which stands the Monument of King Chulalongkorn and King Vajiravudh.
