Collector Sullivan became the first European resident the next year, when he built a seasonal residence on the plateau. He reported to the Madras Government on the mildness of the climate. Europeans soon started settling here or using the plateau as a summer resort and homes for retirees. In 1870 the practice began of key government personnel moving to the hills to conduct business during summer months in this more temperate climate. By the end of the 19th century, the hills were completely accessible, as several Ghat roads and the railway line had been constructed.
