Caerphilly Castle is a Grade I listed building and is the largest medieval castle in Wales. Its cultural and historical significance makes it one of the finest examples of a concentric castle in Europe.

The project provided footpaths, ramps and steps to the Inner Ward and Guard Rooms along with associated retaining walls barriers, landscaping and drainage, and improve the site for events through the installation of lighting and electrical sockets.

Alongside these works despite carrying out the works during a national pandemic, we provided a wide range of social value benefits, including supporting a local mental health charity, providing virtual work experience, trainee weeks, site tours and career films to schools and colleges across the Caerphilly and Gwent regions, recycling 97% of waste, and local supply chain opportunities.

The development is part of a wider masterplan for Caerphilly Castle, which comprises eight projects aiming to enhance tourism and improve the experience for the growing number of visitors.

This is the latest in a series of historic Cadw projects that TC has worked on. The architect and lead consultant was Austin-Smith:Lord. Encon Construction also employed archaeologists to have a watching brief – the castle is a Schedule 1 monument, to ensure no damage to anything of historical value while the work is carried out. The project team also includes engineering firms, Holloway Partnership and Ramboll.
