The Hastings Contemporary, formerly known as the Jerwood Gallery, has reopened to the public under its new name.
It closed for three weeks after the gallery's major backer, the Jerwood Foundation, withdrew its funding along with all of its art works.
But thanks to a recent anonymous donation of £250,000 and a £400,000 grant from Arts Council England in 2017, it has reopened.
On show is work from British painter Roy Oxlade, Danish artist Tal R and Hastings local Sir Quentin Blake.
Since opening in 2012, the gallery has welcomed more than 300,000 visitors.
The gallery was officially opened by the chair of the Arts Council England on Saturday.
