Hildasholm, first called The Stone Court (Stengården) was built in 1910-1911 by the medical doctor and author Axel Munthe. At that time he was well known in Sweden as the builder of his Capri-estate Villa San Michele and for being special physician to the royal family and individual cherisher of the Swedish Queen Victoria.

Axel Munthe had since young days a tender passion for the country around Lake Siljan and especially the rural district of Leksand. Those feelings for nature was associated with ruling National Romanticism that reached a height during the end of the 19th century and the beginning of the 20th century. Influenced by this Axel Munthe chose a beautiful site close to Leksand Church where he realised the building which became the family's summer estate.

The architect was Torben Grut and a local building contractor Hallman's Per Karlsson from Tibble in Leksand was commissioned to build the mansion.

The house was a gift to Axel Munthe's young English wife Hilda, née Pennington Mellor – they were married in 1907. Hilda Munthe and her sons Peter and Malcolm – but seldom Axel – came to Hildasholm at Midsummer. After Hilda's death in 1967 the estate has been named Hildasholm.
