Sylling is located on Holsfjorden, the southeastern arm of Tyrifjorden. Sylling is known for agriculture, particularly the cultivation of fruit. Local farms have a long history of cultivation of strawberries and vegetables. The good soil is due to gravel after the Last glacial period including Sylling-moraine. Its population is about 1700.
Pilgrims' Way (Pilegrimsleden) must have passed Sylling and stopped at the local Olav's spring (Olavskilden). The pilgrims arrived on foot or they could travel by boat across Holsfjorden. During the Civil war era in Norway, King Sverre and the Birchleg forces overcame the Bagler forces of Magnus V at the Battle of Hørte Bridge (Slaget ved Hørte bro) during the Summer of 1178. The victory was the first of many for Sverre. Subsequently, during autumn, the Birchlegs went north to Trøndelag and won control of Nidaros.
