Statement of Special Interest
Originally named Cromar House, the house was built as an autumn shooting lodge for the Marquis of Aberdeen. As Lady Aberdeen wrote in their reminiscences,"At last we found the site for the new house at Cromar. A. has been looking for one for 30 years and now we discovered the perfect place,our Highland retreat in a fashion after our own hearts, with terraces and grass walks, and an Italian garden in the midst of that wonderful panorama of hills.There among the delectable mountains we have settled down". The Cromar estate was sold in 1905 to settle the Marquis and Marchioness' bills, largely run up through their public service work, and purchased by India cotton baron Sir Alexander MacRobert. Rachel Workman, Lady MacRobert later renamed the house Alastrean in memory of her sons (Alastair, Roderic and Iain) who died serving in the RAF in World War II. Lady MacRobert dedicated the house to the RAF in 1943 as a retirement home, forming part of the McRobert Estates Trust. Alastrean House was delisted due to extensive fire damage in 1958. However, as the interior has been sensitively restored and the characteristic main stone structure was undamaged it was listed at category B in 2003.
