Solomon Andrews (1835-1908) was a successful businessman who built a number of houses in Cardiff and owned a transport company there.

He bought Plas Glyn y Weddw in 1896 and established a public art gallery here.

Wales' Oldest Art Gallery: In 2007 Oriel Plas Glyn-y-Weddw celebrated its centenary-and-a-half making it not only one of Wale' most picturesque art venues but also its oldest. Nestling in the village of Llanbedrog on the Llŷn Peninsula, in an area of outstanding natural beauty, the Gothic styled Mansion was built in 1857 as a Dower house for Lady Elizabeth Jones Parry of the Madryn Estate. Lady Love had a substantial art collection and the mansion was designed to purposely house her collection.

Oriel Plas Glyn-y-Weddw houses a fine collection of Swansea and Nantgarw porcelain, which is on long term loan from the Andrews family.

This porcelain was produced between the years 1813 and 1820. It was the result of the dream of one man, William Billingsley, who trained as a decorator at the famous works at Derby, graduating to the position of chief decorator. His dream was to produce the finest porcelain in the world, an achievement generally accepted at that time as being held by the factory at Sevres in France.

Two stones commemorating early Welsh saints are on permanent loan to Plas Glyn y Weddw.

In the early 1830s these two inscribed stones were discovered in Cae Maen Hir, 150 yards north of Tir Gwyn in the parish of Llannor (approximately 4 miles from Plas Glyn-y-Weddw).
