In Reykjavik, the complete tour of the three most famous places in Iceland starts in the capital (Thingvellir) then continues towards the Ring Road 1 north, and then take the 36. The first thing we came across was Pingvallavatn, the largest lake in the entire country (84 km2). It is situated in the valley of Thingvellir. It is relatively close to Reykjavik. Near this lake there is a large open area with many stone mounds (cairns). In modern times, the cairns have emerged as benchmarks. In antiquity they were erected as sepulchral monuments, or used for astronomical reasons.
