Clun Castle is a ruined Welsh border castle on a rocky mound beside the River Clun, on the edge of the small, picturesque town of Clun. Founded shortly after the Norman Conquest, it still has its tall 13th century keep, which unusually sits on the side of the mound, along with extensive earthworks to wander around.

Tip: Wear sturdy footwear as the grounds have steep slopes and uneven ground; there is a free car park next to the castle, with toilets, reached by a footbridge with steps.

Stokesay is a moated, walled manor house near Craven Arms. Though it looks like a castle, it was really a lightly defended mansion, with work completed by 1291. The stone hall and solar block sit behind two stone towers, and the hall keeps its 13th-century wooden-beamed ceiling. The timber and plaster gatehouse at the entrance dates from the 17th century.

Tip: Book advance tickets online through English Heritage, and finish with a break in the tearoom, which is open to all and welcomes dogs.

Whittington Castle stands in the village of Whittington in northern Shropshire, close to the Welsh border and the old fort of Old Oswestry. It began as a motte-and-bailey castle and was rebuilt in the 13th century, with buildings along a curtain wall, five towers on a raised platform, a moat and an outer gatehouse or barbican.

Tip: Look for the viewing mound in the centre of the site, which may be the oldest of its kind found in England.

Pontcysyllte Aqueduct carries the Llangollen Canal across the River Dee in the Vale of Llangollen. Designed by Thomas Telford and William Jessop, it is a cast iron trough held 127 ft (39 m) above the river on eighteen hollow masonry piers, with 19 arched spans. It is 336 yards (307 m) long and about 12 feet wide.

Ludlow Castle is a partly ruined medieval fortress in the Shropshire market town of Ludlow, standing on a high promontory above the River Teme. Probably founded around 1075, it was one of the first stone castles built in England and later became the seat of the Council of Wales and the Marches.

Tip: There is no parking at the castle itself, so plan to park in the town and walk in.

Shrewsbury Castle is a Grade I listed red sandstone castle standing on a hill in the neck of the River Severn's meander. Ordered by William I around 1067, it was extended as a base for operations into Wales. Parts of the original medieval structure remain, including the inner bailey.

Tip: Access to the castle grounds is free, so you can look around them even if you don't go into the museum.

Plas Newydd in Llangollen was the home of Lady Eleanor Butler and Sarah Ponsonby, two Irish ladies who eloped and set up house together in the late 18th century. It began as a five-roomed stone cottage and was enlarged with many Gothic features. It is now a museum.

Tip: Look closely at the outside of the house as well as the rooms, since the patchwork of reclaimed oak carvings is its most unusual feature.

Pitchford Hall is a Grade I listed Tudor country house about six miles from Shrewsbury, built around 1560. Its timber-framed, black-and-white look is striking, and the estate has an orangery and walled garden. Queen Victoria stayed here as a young princess, and during the Second World War the house was chosen as a possible retreat for the royal family.

Tip: Tours of the hall, grounds and treehouse need to be booked in advance through Invitation to View.
