From 1886, during Josiah Sanders Teulon's time as principal, the college experienced a gradual decline in students. This was exacerbated in 1899 when he resigned but retained his income as a resident canon. At a meeting of the college council, it was resolved to close the college. However, the vice-principal made a successful case for continuing and Herbert Rickard was appointed the new principal.
In 1903, a hostel in West Street, Chichester, was bought for £1000 by the college council, the balance being paid by the principal in memory of his wife. This was refitted and became the college headquarters. This hostel was sold in 1919 and the proceeds went towards the purchase of new headquarters in Westgate, Chichester, for £3500. On 1 May 1919, the college was formally reopened by Bishop Charles Ridgeway (his last episcopal act) and was dedicated to St Richard of Chichester.
During the Second World War the college was forced to move temporarily to Cambridge while its buildings in Chichester were used by the military authorities. At the end of the war, the college buildings were sold, except for Marriott House, which was used to house the reopened college from 21 October 1946.[4] New residential accommodation, named Gillett House, was designed by Ahrends, Burton and Koralek, now a Listed building.[5]
After the closure of Chichester Theological College in 1994, its theological library was transferred to the University of Chichester.[6] In addition, St Bartholomew's Chapel, which served as the chapel to the theological college, is now the chaplaincy building of Chichester College.[7]
St Bartholomew's Church after being vacant since 2015 when the 10 year lease to Chichester College as a performance space ended, was sold to a local family partnership as an arts and community hire venue called the Chichester City Arts Centre. The centre is also the home of the Rosemary Bell Academy of Dance, a local 10 year old school for teaching classical ballet to the Royal Academy of Dance (RAD) syllabus to children of pre-school and school age as well as adult students. The centre opened in September 2022.[citation needed]
