You'd never know this floating hotel coming to London's Thames was once a Dutch prison

A floating hotel that was once a prison in the Netherlands is being towed 311 miles to the River Thames, where it will become London's latest luxury hotel.

The Good Hotel opened in Amsterdam in 2015, and will relocate to Newham's Royal Docks in September, according to the hotel's website.

The 144-room pop-up hotel was converted from a detention centre in 2012, The Mirror reports.

Transporting the barge will take a floating platform, a submerged barge, and tow boats, according to The Mirror.

While staying in a prison cell might not be everyone's idea of a holiday, The Good Hotel Group has transformed the barge into a stylish modern base within close proximity of the city centre.
