No more than a few minutes drive from Ullswater, and about four miles south of Penrith, an elegant Georgian mansion nestles in the valley. But the mid 18th century architecture is somewhat deceptive. The origins of this manor house date back to the times when Scottish invaders proved a constant threat to land owners living along the borders, and many fortified towers were erected as some protection to them and the country.

Today, Dalemain is home to the Hasell-McCosh family, and has been lived in by several generations of Hasells since 1679. When Sir Edward Hasell bought Dalemain from the Layton family, a medieval hall, and two Tudor wings, had already been added to the 12th century pele tower. By 1750 his son had carried out a major remodelling of Dalemain, culminating in the complete enclosure of the existing buildings within a Georgian facade. Dalemain's appearance has changed little in the last 250 years, but the internal rooms reflect the varying periods of occupation.

The Old Hall is an impressive example of original medieval architecture, albeit enhanced by the addition of a later ceiling, and is typical of a period when large, open halls would form the core of both domestic and business activities. In the old Norman pele tower, some of the upper chambers have been given a 16th century makeover with rich oak panelling to the walls and, in one room, a superb plastered ceiling completes the Tudor influence. The basement now houses a museum, created to commemorate the Westmorland and Cumberland Yeomanry. During the 19th century, Edward Hasell was Colonel of the Dalemain Troop for forty years, and there is much memorabilia displayed from his time. From the collection of early 20th century toys in the day nursery, it appears that this part of the house was a popular haunt with the children until the 1930s.

Reflecting the major works carried out during the 18th century, the main rooms at Dalemain have been decorated largely from that period. Ornately carved chimney pieces, high quality English furniture, and many family portraits give Dalemain an air of refinement. At the same time it remains a much-loved family home, and has an inviting warmth that welcomes visitors inside to get to know those people who have helped to shape Dalemain over the last three centuries.

Not only does the house contain a few surprises. Dalemain is surrounded by gardens, walks and woodland that have been continuously cultivated by the ladies of the house since the early 19th century, each facing their own challenge. The results are stunning, and bring together the exotic and indigenous varieties in a year-round display of colour and interest.
