WorldYellow In detail

Near Wassu village is located the richest site in Gambia – 11 Wassu stone circles. These perfectly shaped stones have been erected here sometimes around 750 AD.


Many local people consider that stone circles have special powers and can be lethal if disturbed. They mention the case of excavations in the 1930s when the leader of the expedition and archaeologist died mysteriously. There are stories about stones that glow in the dark and powerful spirits lurking near these circles.

This adds charm to Wassu stone circles and certainly has helped to preserve these stones throughout the centuries.


Stone circles most likely were created by the local Serer culture. In this region (Senegal and Gambia) are found more than 1,000 such megalithic monuments which were created in the time period from the 3rd to 16th century AD.

According to the results of excavations (not the deadly ones but later expedition from the 1960s) Wassu stone circles were erected in the 7th – 9th century AD. Purpose of this work is not known.

Some centuries later, in the 10th – early 14th century in the centre of stone circles were buried important persons. At the end of this period here were buried some Islamic scholars thus further increasing the importance of stone circles among the locals.

Nowadays local people leave smaller stones or vegetables on the top of flat megaliths as offerings for better luck.

In 2000 there was built small museum next to the stones and since 2006 when the site was included in the UNESCO World Heritage list, Wassu stone circles belong to the most popular tourist destinations in this region.

Wassu stone circles have a diameter of 4 – 6 m. In each circle are 8 – 14 standing stones, next to the circle stand so-called "frontal stones".

Stones are made from laterite – sandstone which is cemented with lime and iron oxides. Initially, this stone is rather soft and it is fairly easy to form it in the needed shape. As time goes on, the stone becomes hard.

Megaliths have been shaped with great skill, most likely with iron tools. Most stones are shaped as round columns, with flat tops. There are also square columns. All stones in a circle have similar sizes and forms.

In Wassu are located the tallest standing stones in the Senegambian group of megaliths. Stones are 0.6 – 2.45 m high and up to 7 tons heavy.
