Which hedge maze is made up of over 16,000 English yew trees?

Longleat is an English stately home and the seat of the Marquesses of Bath. It is a leading and an early example of the Elizabethan prodigy house. It was the first stately home to open to the public, and the Longleat estate includes the first safari park outside Africa.

The Longleat hedge maze is considered the world's longest, with 1.69 miles of pathway. It is constructed using more than 16,000 English yews forming the walls surrounding a central tower and features six raised footbridges.

A hedge maze is an outdoor garden maze or labyrinth in which the "walls" or dividers between passages are made of vertical hedges.
