A unique "multiversity" higher education project is expanding again with another new building being opened.
The universities' shared library is based in an old navy drill hall
The University of Kent's Gillingham Building will welcome students at its shared Medway campus with Greenwich and Canterbury Christ Church universities.
The three universities and Mid Kent College now have a combined 9,500 students at the Chatham Maritime site, a five-fold increase since 2002.
Thames Gateway boss Judith Armitt was opening the new building on Friday.
The University of Kent said it would house teaching rooms, academic offices and IT suites.
Spokesman Jeff Brown said the "groundbreaking" shared campus was now becoming "as significant" to the Medway area as the Chatham naval dockyard was 400 years ago.
Comparing the multiversity idea to more traditional university campuses, Mr Brown said: "We're the new one, we're going to move this forward."
It is hoped student numbers will soon exceed 10,000.
