Chandraketugarh, dt. N-24 parganas
The early historical site Chandraketugarh, is located at Mouza Hadipur about 45 kms north.east of Calcutta. Previously, a small scale excavation was carried out at the site by the University of Calcutta in 1956-57. The archaeological findings also proved that the area around Chandraketugarh was the center civilization right from fifth-fourth century B.C. to the medieval period. As the excavation carried out by University was in small scale, very little could be known about the city planning, architecture, ramparts etc. To more about the cultural sequence of the site, city planning, settlement pattern and ramparts etc excavation was conducted at the site during the field season 2000-2001. The eastern rampart area of Chandraketugarh was selected in the first instance for excavation. A vertical trench was laid across the rampart towards its eastern edge in east-west orientation. At a depth of about 2.75m from surface brick soling has been noticed on the section. Traces of wooden logs have also been noticed. Among the antiquities mention may be made of bone points, dice, terracotta ball, fragmentary terracotta plaque with an elephant on it, and a broken red sandstone grinding material. The discovery of a terracotta mithuna plaque from surface is noteworthy. The ceramic type includes grey ware, dull red ware and red ware. The main shapes are vases, bowls, miniature pots, handis etc. having decorations in the form of parallel incisions, chequered pattern criss-cross designs etc. Due to high water table excavation work could not be continued up to natural layer.
