Across the laterite plains and hills of Kerala stand distinct prehistoric burial monuments. They are practically unique to the region. The most famous sites include Cheramanangad (known as Kudakkalluparambu) and Porkkalam in Thrissur. These monuments are the Kudakkallu (umbrella or hood stones) and Topikkallu (hat stones).
These structures date to the Iron Age megalithic period. They served as secondary tombs for the deceased. The Topikkallu was built with four dressed, triangular laterite stones (clinostats). They were planted in the ground and slanted inwards. They formed a truncated square pyramid with flush, interlocking vertical joints. A heavy, dressed hemispherical capstone rests on this base. It resembles a low-crowned hat or dome. At some sites, 5 to 12 supporting stones were used in a circle. They formed a “multiple hoodstone” that enclosed a wider area.
The Kudakkallu, meanwhile, consists of a low burial chamber. It is covered by a wide, plano-convex laterite capstone shaped precisely like the traditional, handleless umbrella made of palm leaves. Beneath these carefully balanced capstones, archaeologists found pyriform burial urns containing fragmentary bones alongside black-and-red ware pottery, iron daggers and axes, and etched carnelian beads. This points to precise mathematical calculations and an advanced mortuary cult among ancient Kerala’s settled communities.
