The homestead sits on Geelong Road on Max Wohlers' property.

Detective Senior Constable Caroline Blackley, of Ararat, said the thieves were at the property between March 24 and April 7.

They cut the wire fence and proceeded to remove "approximately 25 to 30" bluestone blocks, Senior Constable Blackley said.

Mr Wohlers said they targeted the shaped blocks from around the two doorways on the homestead.

"You could never replace it," he said.

"They've taken what they could lift. They are pretty heavy, those stones.

"What they've done is cut the fence and then carted them out.

"They've also knocked down the entire back wall.

"They've probably taken them to put around their garden or by their fire places, because the ones they've taken are the ones that have been nicely shaped."

Mr Wohlers said the property had been in his family for years, and was very popular with photographers and couples getting married.

"It's got no roof on it but there are quite a lot of people who use it to take wedding photos," he said.

"Once they (thieves) wreck it all you won't be able to do those sorts of things."

The family has looked after the property for decades.

"Dad had most of the land since the early 1940s," Mr Wohlers said.

"It's been our possession for a long time."

This isn't the first time the Wohlers property has dealt with thieves.

"We've always got people pinching stuff around here, pinching wood and livestock," Mr Wohlers said.

Senior Constable Blackley asked anyone with information to speak to Ararat Police or call Crime Stoppers on 1800 333 000.
