About

Newark Castle, on the south shore of the River Clyde in Port Glasgow, is one of Scotland’s finest and best-preserved Renaissance residences, with origins dating back to 1478. Built by George Maxwell as the “New Werke of Finlaystone,” it began as a fortified tower house and gatehouse within a walled courtyard. In 1597, Sir Patrick Maxwell, a powerful yet notorious laird and associate of King James VI, transformed it into the elegant three-storey mansion seen today, linking the original structures with a richly detailed north range. The castle’s crow-stepped gables, corbelled turrets, and fine stonework reflect the Scottish Baronial style, while its interiors reveal vaulted cellars, a grand hall, and refined living spaces. Once surrounded by shipyards, the site now enjoys open views across the Clyde, offering a striking contrast between its medieval past and industrial heritage. Managed by Historic Environment Scotland, Newark Castle stands as a rare blend of fortress and stately home, telling stories of power, ambition, and survival over five centuries.
