The inner east gatehouse is perhaps the most impressive part of the castle. Until as recently as the 1930s, only the rear wall of the medieval building was left standing. The marquess of Bute had the shell of the gatehouse restored, but some parts, including the floors of the first- and second-floor rooms, were left unfinished.
Cadw is bringing this building back to life so visitors can experience the great rooms it contains and the magnificent views from the rooftop. This involved conserving the stonework, adding new gutters to stop the rain pouring back into the building, laying new wooden floors, making the staircases safe, and fitting new doors and windows.
Now the work is complete, visitors are free to explore the gatehouse and to walk along the curtain wall behind the 'leaning tower', along the Braose gallery and into the south-west tower. These parts of the castle have been closed for fifty years.
