The university opened the state-of-the-art facility early on Thursday, 17th October.
The complex is expected to accommodate over 1,200 students, who compete in sports across the university every year.
Team Solent competes in several high-level leagues at both local and national level, with over 30 sports clubs.
(A game of basketball was one of the first events to kick off proceedings for the complex's official unveiling)
The university is also one of the first in the UK to develop sports-based, undergraduate courses.
Their reputation in these areas have grown to the extent of being named Most Improved University at the British Universities and Colleges Sports (BUCS) National Awards in 2017.
Martin Nailor, Head of Solent Sport and Will Cope, Sport Journalism course leader were both present.
