At the heart of Lydiard Park is the grand neo-Palladian house. Originally in the hands of the Viscounts Bollingbroke for many generations; it was renovated and opened to the public in the 1950's. It lies within the manicured grounds of the estate along with a church and ornamental lakes.

The house underwent many alterations over the years as it passed down through the family line, reaching a prominence in the early 19th century. By the time of WWII however, it had fallen into a poor state of repair and the grounds were even used as a German prisoner of war camp. After the end of hostilities the Swindon Corporation purchased the house and restored it back to its former glory and it was subsequently opened to the public.

The grounds of the estate have played host to numerous concerts and festivals over the years and has become quite a popular venue. As well as the large scale productions there are also many other events throughout the year such as nature walks, etc.

Like most public places if you wish to visit with birdwatching as your main aim, then early mornings are best, before the park gets too busy. There are various wooded area throughout the grounds which host species such as Coal Tit, Nuthatch, Treecreeper and all the usual woodland birds. Song and Mistle Thrushes are quite numerous and there are often plenty of gulls around as well. The surrounding fields are also worth scanning as Hobbies frequent them; other birds of prey have been sighted there too. Although not particularly large the lakes attract a fair number of birds, including Grey Wagtails, Coots, Moorhens and impressive numbers of Little Grebe - 37 on one count!

The main entrance and parking area is off the minor road between Freshbrook and the village of Hook, where there is ample parking spaces. You can also walk there from Grange Park and Middleleaze.
