Three of the eight H-Blocks in the Maze Prison have closed due to the early release of prisoners under the Belfast Agreement.
The Northern Ireland Prison Service said the Maze population was down to 304: 250 convicted paramilitary prisoners, 31 on remand and the remainder "ordinary" criminals serving short sentences.
H-Block 8, which had housed IRA inmates, was closed last week, and blocks H1 and H2, containing UVF men, closed on Monday.
