This is a relatively easy to find quick cache, but the road can be busy at times, so look out for muggles.
Newbury Hall was built in 1859 as a school for local children. The building still survives as a school, but is now home to international boarding school students from many different countries around the world. This is a nano cache (sorry), so you will need to bring your own pen and there is no need to enter school property to find it. The location is opposite the school at approximately adult head height. On road parking is possible for limited periods.
