Glynllifon Country House

Caernarfon, United Kingdom, United Kingdom

---

Glynllifon Country House, more formally known as Plas Glynllifon, is a Grade I listed neoclassical mansion on the Glynllifon estate near the village of Llandwrog, just south of Caernarfon in Gwynedd, North Wales.

The present house dates from 1836–1848, designed by architect Edward Haycock, and was later extended in the late 19th century, making it one of the most important and architecturally complete country houses in the region.

It sits within a large landscaped park that once belonged to the Barons Newborough and includes formal gardens, woodland, and historic estate buildings such as a Grade II listed walled garden and gardener’s cottage.

The mansion has served over time as a private family seat, college offices and dormitories, and in recent decades as a privately owned country‑house hotel and wedding venue, prized for its grand interiors, parkland setting, and views across the Llyn peninsula toward Snowdonia.
