History
Built by the 3rd Lord Newborough continuing his brother's many improvements to the pleasure grounds begun in 1820's. Provided water for the many water features in the pleasure grounds.
Glynllifon was the seat of the Wynn family and Sir Thomas John Wynn became the 1st Lord Newborough in 1776. The house was rebuilt after a fire 1836-48 by Edward Haycock, architect of Shrewsbury. Influence for some of the garden features came from the family’s grand tours.
