The gold rush brothel run by President Trump's grandfather will be turned into a tourist attraction.

Friedrich Trump built the Arctic Restaurant and Hotel in Bennett, Canada, and kickstarted the family's multi- billion empire.

On the surface, his business was simply a hotel and restaurant that boasted a fancy menu - in reality, it was a brothel that housed prostitutes and sold large amount of alcohol, Maclean's Magazine reports.

The Parks Canada and the Carcross Tagish First Nation want to transform the ancient site into a tourist attraction, 120 years since its founding.

Trump - who was working as a barber - moved from Manhattan, New York, to Bennett to start the business in 1897.

The German-born immigrant was attracted to the Klondike Gold Rush in Bennett.

When he arrived, he employed indigenous people in Canada to help him construct the building.

The hotel sold dishes considered expensive at the time, including moose, goose and caribou.

Prostitutes - who called themselves 'Ladies of the Night' - often stayed at the hotel to entertain guests.

One hotel reviewer wrote at the time: 'For single men the Arctic has excellent accommodations as well as the best restaurant in Bennett, but I would not advise respectable women to go there to sleep as they are liable to hear that which would be repugnant to their feelings - and uttered, too, by the depraved of their own sex.'

In 1901, Trump left Bennett since the gold rush was over and moved his business to Whitehorse, Canada. He later sold the restaurant because the government at the time was suppressing alcohol, gambling and prostitution - the main sources of his profits.

He then moved back to Germany - which he left at the age of 16 years old - and met his wife Elizabeth.

The pair had three children together: Fred - the president's father, John and Elizabeth - and eventually returned to the US.

President Trump has called reports of his grandfather running a brothel 'totally false'.

The renovators are yet to say when the site will be open to the public.
