Trematon Castle has a 12th century keep like nearby Restormel castle. It was built on the site of a Roman fort in a Motte and Bailey style. You can visit the castle but it's only open on Thursday, Friday, and Saturday. You also get a good view from the footpath as you walk past.

This 17th century defense is still in use by the British military as the base of 29 Commando Regiment of the Royal Artillery. It was originally built as part of defenses against the Dutch.

Radford Park is a beautiful green space on the edge of Plymstock with a rich history. A grand Elizabethan property stood in the park originally, Radford House, owned by the Harris family for over 500 years. Hosting parties attended by figures such as Sir Walter Raleigh and Sir Francis Drake, this was quite the place to be seen. Demolished in the late 1930s after falling into disrepair, only the grounds remain. The park is free to walk around and offers many interesting sights and viewpoints including over Hooe Lake. The 19th-century castle is a particularly pretty sight and marks the end of the West Devon Way.

This dramatic 17th-century fortress was built to defend the coastline from the Dutch. The fortress, owned and managed by English Heritage, is still used by the military today.
