Plas Mawr
About
Robert Wynn, a merchant who had made his money and wanted everyone to know it, built Plas Mawr on the High Street between 1576 and 1585. What survives is the reason to come: elaborate moulded plasterwork across the ceilings and overmantels, largely as it was left, in a town house rather than a country seat. Cadw runs it with an audio tour. Two practical things govern a visit. It closes completely for the winter, from 2 November to 28 February, so a December or January trip to Conwy simply does not include it. And last admission is 45 minutes before closing, which is longer notice than most sites give, because the tour takes time. Admission at the 1 June to 31 August 2026 band is £10.90 adult, £9.80 senior, £7.60 junior or student, £34.90 family, free for members and under-fives.
