The Old Collectorate Building in Tiruchirappalli — historically known as Rani Mangammal Mahal — is one of Tamil Nadu’s most important heritage structures, reflecting the architectural grandeur of the 17th century. Constructed by Chokkanatha Nayak of the Madurai Nayak dynasty, this palace originally served as the Durbar Hall when Tiruchirappalli acted as the capital during significant periods of the Nayak era. Later, under British rule, the palace was repurposed as the District Collector’s office and became commonly referred to as the Collectorate building.

Architecturally, Rani Mangammal Mahal is notable for its blend of Nayak and Indo-Saracenic elements — a style characterized by large arched verandahs, stucco ornamentation, circular colonnades, decorative minarets, and expansive halls designed for public functions and governance. Its spatial planning, high ceilings, and horseshoe arches were intended to provide natural ventilation and comfort in Tiruchirappalli’s tropical climate. The palace shares visual affinities with the famous Thirumalai Nayakkar Mahal in Madurai, especially in the use of proportion, symmetry, and sculptural detailing.
In recent years, the Tamil Nadu Public Works Department (PWD) has undertaken a major conservation and renovation project to restore the building to its former glory. Sanctioned with an estimated budget of about ₹9.40 crore, the project was progressing rapidly with nearly 70% of the work completed by March 2024. This effort has focused on structural stabilization, conservation of original features, and careful repair of deteriorated elements, using traditional materials and methods to preserve historical authenticity.
Today, the historic palace also houses the Government Museum, Tiruchirappalli, showcasing artefacts and inscriptions from the region’s long past. Once fully restored, the building is expected to not only continue as a repository of local history but also become a vibrant cultural landmark that attracts scholars, students, and tourists alike.
