George Macartney, when visiting the summer retreat of the Chinese emperor in Chengde in 1793, could compare the magnificence of what he saw only with Lowther Hall: “If any place in England can be said in any respect to have similar features to the western park, which I have seen this day, it is Lowther Hall in Westmoreland, which (when I knew it many years ago) from the extent of prospect, the grand surrounding objects, the noble situation, the diversity of surface, the extensive woods, and command of water, I thought might be rendered by a man of sense, spirit, and taste, the finest scene in the British dominions.”[16] In 1839 Mrs Harriette Story Paige visited Lowther Castle with Daniel Webster, a famous American politician.

“Lady Gladys Herbert and Later Countess of Lonsdale was superbly beautiful, with brilliant colouring and the features and carriage of an ideal Roman Empress.
As we wisked through the Park and the impressive walls of Lowther loomed before us she intimated that the one thing she was most anxious for me to see was the emu strutting about the grass.

The couple then lived near Oakham and Grace became pregnant but suffered a bad fall while hunting and lost the baby.
[29] In August 1895 the Kaiser visited Lowther Castle for some grouse shooting, and the imperial flag flew over the house.
During the First World War he helped to found the Blue Cross animal charity, where his chief role was as a recruitment officer of both men and horses.
His brother Lancelot, the 6th Earl, inherited the estate in 1944; but because of Hugh's large debts he was forced to sell many of the family's treasures.

A report in October 2018 summarised the situation at that time as follows: "The part-demolished castle shell and the wrecked garden have been resurrected with impressive energy and conviction.
Work on the 130-acre garden was continuing in mid-2019, based on plans by Patrick James and Dominic Cole, under the guidance of designer Dan Pearson and the castle's current owner Jim Lowther (son of the 7th Earl of Lonsdale).
[40][32] One of the projects is the Garden in the Ruin, a new phase after the 2015 plantings, including Hydrangea aspera Sargentiana and Parthenocissus henryana.
The new Rose Garden had already received 1,250 eglantine roses, underplanted with brunnera, Galium odoratum and Chaero-phylum hirsutum Roseum; in spring 2019, 6,000 perennials were added, white Geranium macrorrhizum White-Ness, Calamintha sylvatica Menthe and Brunnera macrophylla Betty Bowring and Narcissus poeticus and Camassia leichtlinii alba.
