But this weekend, the 1870s-built Grossmann House will reveal its after-dark secrets when Newcastle Ghost Tour participants weave their way through the building.

Newcastle Ghost Tour owner Renata Daniel and Anne Rzechowicz will be leading the tour at historic Grossmann House on Sunday night.

"This is different from our normal tour. It coincides with the anniversary date of Evelyn the ghost," Ms Daniel said. "Ever since we started at Grossmann House, we heard this beautiful tale of a school girl called Evelyn.

"We know she tends to to appear on June 30, that's her anniversary of appearance. So we decided that would be the day for our event every year.

"We have a whole crew of people coming - all dressed up in school uniform and we are going to bring her back as well as any of the other ghosts here."

Ms Daniel, who has worked as a psychic and ghost tour operator, also leads a number of tours around the region.

Between 1892 and 1963, the building housed Maitland Girls' High School - which was one of the first four public high schools established in the state.

"There are different bits and pieces of history about Evelyn however we haven't been able to pinpoint her full history," Ms Daniel said.

"We've been told she drowned in the well and that she appears there because that's where she died."

A light supper including tea, coffee, sausage rolls "with plenty of sauce" as well as lollies will be served.

"We still have a few tickets left," Ms Daniel said.

"We will play some games that kids would've played then. It will also be about the investigation including all the normal paranormal parts such as the spirit box.

"People forget that it was a school, and the history of the children and teachers is fascinating. We have lots of stories."
