The Archaeological museum at Thrissur is located in the Kollengode Palace, which is an architectural delight. This magnificent building houses a collection of murals from all over Kerala and preserves an extraordinary treasure of Veerakallu (Veerakallu or hero stones are stone engravings and sculptures of heroes of the bygone era), temple models, olagrandhangal (manuscripts on dry palm leaves), megaliths etc. It is interesting to note that most of the exhibits at the archaeological museum were recovered from the forests of Thrissur and Wayanad.
