Revdanda Fort (रेवदंडा किल्ला / Fortaleza de Chaul)

The Coastal Bastion of Chaul: European Fortress to Maratha Konkan

Stretching along the black sand beaches at the entrance of the **Kundalika River estuary** in Revdanda, Alibaug taluka, Raigad district, Maharashtra, **Revdanda Fort (रेवदंडा किल्ला)**—historically celebrated as **Fortaleza de Chaul**—is one of the largest and most architecturally imposing European coastal fortresses in western India. Constructed by the **Portuguese Empire between 1524 and 1577 CE**, the fortress was built to protect the ancient international maritime emporium of **Chaul**, which had traded with Ptolemaic Egypt, the Roman Empire, and Persia for millennia.

The Portuguese engineered an enormous stone defensive enceinte covering over 5 kilometers, reinforced by heavy artillery bastions, deep moats, and coastal battery platforms. Inside the walls, a grand colonial European settlement flourished, complete with churches, monasteries, hospitals, and the iconic **Saat Manzili** (Seven-Storeyed) watchtower. In **1740 CE**, following the surrender of Vasai, Maratha forces led by **Chimaji Appa** negotiated the treaty transfer of Revdanda Fort, absorbing the colossal citadel into the Maratha coastal defense network. In 1818 CE, following the fall of the Peshwas, the British East India Company took control of Revdanda.
