Sitting within the site is the Kings Bridge Bar and Restaurant, originally the old corn mill house, built in the 1800s.

The building was originally constructed for Andrew Gatenby who arrived in Tasmania in 1823 with his young family and sat between Ross and Cressy on the banks of the Isis River, once called the Penny Royal Creek.

The timber addition to the mill, named Barton, was completed in 1825 and the stone portion in 1840.

With his seven children, Mr Gatenby used about 6000 stone blocks and a number of large timber beams to construct the ambitious project.

Over the years, the farmhouse and mill house fell into disrepair but rather than demolishing the historic building, it was decided that the complex should be moved to its current site in Launceston.

Once the decision had been made to move the building, the stones were all numbered individually, stacked up and carted to their new home.

Other parts of the Penny Royal site were later built out of stone from the same quarry as Mr Gatenby's mill.

Looking around the restaurant today, it is easy to imagine the world that Mr Gatenby and his family once lived in.

Two-century-old bricks line the walls, most still in the same condition as they were when they were first moved from their original home.

Most impressive of all is the lodge — a quiet offshoot of the building.

This room features no windows and has not been renovated since it was first built so many years earlier.

As the fire crackles and guests are taken back to another time, the charm and history of this restaurant truly comes alive.

Restaurant owner Asli Dastan said that to own such an important piece of Tasmania's history was an honour.

"It's a really historical, beautiful building and I just love it," Mrs Dastan said.

"The bar area and the lodge are in original state because they were able to move the whole establishment together.

"To number these stones one by one, it's a hard task. It would have been such a hard job when they moved all the bricks."

Originally from interstate, Mrs Dastan said it was the Kings Bridge that initially made her fall in love with Launceston.

"I love it here. The building is just so amazing and it's an amazing opportunity to work here," she said.

"I fell in love with Launceston because of Kings Bridge and this building. There's nothing quite like it.

"It's a really charming, comforting space, it's so amazing. It's always been used as an establishment to host guests."
