History

The former home of the Mostyn family, after the Crown the oldest landowning family in Wales, and responsible from the mid C19 for the development of Llandudno as a resort. The land was a property of the Mostyn family from the C15. The oldest part of present building dates from the early to mid C16, or earlier, from the time of Margaret Mostyn (a contemporary poem may refer to building of the Hall in her time). This block runs roughly E-W. There is a crosswing to the E of c1700, and to the W, large additions of the later C19, when architects active on the estate included E W Nesfield, who designed the large W wings, and John Douglas.
