Historical roots

Kollam (Quilon) was one of the most important ports in medieval Asia, the terminus of the Arab trading vessels that brought the world's demand for Kerala pepper. The Kollam Era (Kollam Andu) dating from 825 CE was the traditional calendar of the Travancore region, showing the city's historical significance as a centre of civilisation. The cashew processing industry, established in Kollam in the 19th century, has made the city the global capital of this trade.

Connectivity

Kollam Junction is a major railway station on the Ernakulam-Thiruvananthapuram line. NH-66 road connectivity. Boat services to Alappuzha along the famous backwater route. Approximately 70 km from Thiruvananthapuram.

Seasonal context

🌿Hemant Ritu — Margashirsha

Onam (August-September) is the most important community celebration. The Ashtamudi Lake backwaters are most scenic post-monsoon. The cashew processing industry peaks during the harvest season (February-May) when raw cashews are processed. Christmas is celebrated with enthusiasm by the significant Christian community. The Kerala Boat Race season activates the backwaters in August.
