Adil Shah Palace

Adil Shah Palace, also known as Idalcao Palace or the Old Secretariat, is a historic heritage building located in Altinho, Panaji, Goa. Originally constructed in the 16th century by Yusuf Adil Shah of the Bijapur Sultanate, it later served as the Portuguese Viceroys' residence and subsequently as the state secretariat. The structure represents a significant blend of Indo-Islamic and Portuguese architectural styles and stands as a prominent landmark overlooking the Mandovi River.

Visitors can expect to view the exterior architecture of this 16th-century heritage building, which features distinct Portuguese colonial modifications over an original Adil Shahi foundation. Located on a hillock in Altinho, the site offers views of the surrounding area and the Mandovi River. As the building currently houses government offices, public access to interiors may be restricted, and visitors primarily experience the historical facade and external grounds.

Originally built around 1500 by Yusuf Adil Shah of the Bijapur Sultanate as a palace and military outpost, it was captured by the Portuguese in 1510. It subsequently functioned as the official residence of Portuguese Viceroys until the mid-18th century when the viceregal seat moved to Old Goa and later back to Panjim. Post-liberation, it housed the Goa State Secretariat until administrative functions relocated.

The palace symbolizes the transition of power from the Adil Shahi dynasty to Portuguese colonial rule in Goa. Its architectural evolution reflects centuries of cultural synthesis between Deccan Islamic traditions and European colonial aesthetics, making it a key monument in understanding Goa's layered history.
