The 80ft B-listed stone landmark was built in 1813 for Francis Gray, the 14th Lord Gray, and is split across four storeys.
An octagonal spiral staircase with small windows sits at the corner of the property and leads owners to each floor of the stone building.
And potential buyers will be able to relax on the rooftop terrace and look out onto stunning panoramic views over the River Tay to the Lomond Hills.
The castellated tower was built in the centre of a deep forest close to another historical landmark, the A-listed Kinfauns Castle.
It has recently undergone some repair work, including the replacement of joists and the addition of a roof to make it watertight from the top.
Estate agents Thorntons are hoping potential buyers will be able to transform the historical landmark into a family home after seeking planning permission.
They described the sale as “a truly rare and unique purchase opportunity”, adding: “The B-listed Binnhill Tower is a stone-built, four- storey, Gothic tower with a stunning hilltop location in the picturesque village of Kinfauns, surrounded by mature woodlands, and with spectacular panoramic views over the River Tay to the Lomond Hills.
“This prominent landmark represents a truly rare and unique opportunity for anyone seeking a historic and romantic building that is ripe for a Grand Designs-style transformation.
“The castellated tower was built by Francis Gray, the 14th Lord Gray, as an observatory and focal point within the luscious estate grounds of Kinfauns Castle, an imposing A-listed Gothic mansion.
“The tower has lapsed planning permission to be restored and converted into a dwelling, and it comes with a small footprint of land.
“There may be potential to negotiate with the Forestry Commission the purchase of additional land as well.”
Thorntons announced the new listing on social media yesterday, saying: “Have you ever dreamt of owning your own fairytale property?
“Perhaps wondered what it would be like to live in a tower, guarded by a dragon, waiting to be rescued by a mighty hero?
“Well, wonder no more.
“As the phenomenal Binnhill Tower has come to market, ready to make your property dream come true.”
