A 22-month, €2.7 million conservation and restoration project is underway at the Royal Chapel of the Sintra National Palace. The initiative focuses on the 15th-century Mudéjar ceiling, one of the oldest of its kind in Portugal, alongside structural reinforcements, roof repairs, and the restoration of wall frescoes and ceramic flooring. The project aims to recover original colours and patterns lost during 20th-century interventions, with visitors able to observe the restoration work in progress from the upper choir.
