The watermill, which dates back to the 1830s, is one of the few restored mills in the region still capable of grinding flour.
The herb garden contains over 200 different species, many of which were traditionally used by the Knights Templar who once held land in the vicinity.
The site is home to a significant population of red squirrels, which are protected and carefully monitored in the woodland areas.
The estate was formerly known as Temple Sowerby Manor, referencing the historical presence of the Knights Templar in the area.
The walls of the garden were constructed from local red sandstone, a material characteristic of the surrounding Eden Valley geology.
Acorn Bank is defined by its sheltered walled garden and the 19th-century watermill powered by Crowdundle Beck. The gardens feature an extensive collection of medicinal and culinary herbs, historically cultivated for the local religious community. The site preserves an industrial history through the fully restored working corn mill, which displays the original machinery used for milling flour. A woodland walk follows the course of the beck, showcasing local biodiversity and seasonal wildflowers. The estate remains a focal point for heritage conservation in the Eden Valley. The main house is a mid-16th-century structure with later Georgian additions, though the interior is not typically open to the public. The grounds are designed to support a variety of bird species and pollinators. It serves as a regional hub for National Trust environmental initiatives.
