There is a small pool in the central part of the Temperate House with some rather large Koi Carp which are easily visible in the picture.

King William's Temple was built in 1837 for Queen Victoria, in memory of William IV, and stands on a mound on Cherry Walk in between the Palm House and Temperate House. The surrounding area has been planted to depict a typical Mediterranean natural habitat and is known, unsurprisingly, as the Mediterranean Garden.

This view is from the Mediterranean garden showing Cherry Walk leading to the temperate House in the distance. King William's Temple is behind the camera position.

Some of the plants to be found here include Stone pines (Pinus pinea), Tuscan olive trees (Olea europaea) and the green spires of Italian cypress (Cypress sempervivens) growing above shrubs such as Cistus and lavender (Lavandula lanata).

A little to the north of the Temperate House is an arboretum which includes a 59 foot high treetop walkway known as the Xstrata Walkway which is accessible to visitors.

You will need a head for heights for this although the walkway itself is quite wide with very substantial rails and if you look at the larger picture you will be able to see people on the walkway which gives a guide to scale.
