Head up Penshaw Hill to see the monument built in 1844 and modelled on the Temple of Theseus in Hephaestus. From the top of the hill you can see for miles. During the summer months the National Trust open up a secret staircase in one of the pillars and you can climb right to the top! Be sure to book your place with the National Trust's Tours to the Top of Penshaw Monument. Back on solid ground Herrington Country Park is just over the road, with its great play area and boating lake - the wide open spaces are perfect for flying a kite.
