A FORMER prison island has been transformed into a huge hotel - and has amazing ocean and mountain views.
Montenegro is soaring in popularity with Brits who want a cheap holiday with beautiful beaches.
But many may not have heard of Mamula Island, built in 1853 as a military fort and named after Austro-Hungarian General Lazar Mamula.
It was turned into a prison camp under Mussolini's rule, with it being notorious for brutal torture and treatment of prisoners.
It was eventually abandoned, and left empty with many of the prison cells remaining untouched.
However, back in 2016 it was revealed that new plans hoped to open it as an island hotel - with Mamula Island Hotel opening earlier this year.

A short boat ride from the mainland, the former 19th-century fortress has retained most of the building, albeit with a modern update.
Guests can choose between rooms and suites, with many of them having ocean views or mountain views.
But the best views are found on the rooftop, with a swimming pool and 360-degree views around the island.
Opt for the speakeasy-esque Pinea Bar, or grab a bottle of Rose to enjoy on the private pebble beach, complete with sunloungers.
