The Coastal Stronghold of Quilon: Portuguese Foundation to Colonial Rivalries

Standing on a wave-swept laterite headland overlooking the azure waters of the **Arabian Sea** in Kollam (historically known as **Quilon**), southern Kerala, **Tangasseri Fort (തങ്കശ്ശേരി കോട്ട)**—originally named **Fortaleza de São Tomé (St. Thomas Fort)**—was one of the earliest fortified European naval enclaves on the Indian subcontinent. Founded in **1518 CE by Portuguese Captain Rodrigues** with permission from the Queen of Deshinganadu (Kollam), the fortress was established to secure exclusive control over the lucrative Malabar black pepper trade.

In **1661 CE**, following intense naval bombardments, the fortress was captured by the **Dutch East India Company (VOC)** under Admiral Ryckloff van Goens. The Dutch downscaled the massive city walls into a compact triangular sea bastion that served as their commercial center for over a century. In **1795 CE**, the British East India Company assumed control of Tangasseri, retaining it as an administrative enclave within Travancore until Indian independence.

"Tangasseri Fort is the laterite sentry of Quilon—where Portuguese galleons and Dutch merchants anchored in search of Malabar black gold."
