Silsako

Silsako was an ancient stone bridge over a channel of river Barnadi (Bornadi) in Hajo, Kamrup.

Invaders like Muhammad bin Bakhtiyar Khalji entered into Kamrup in the year 1205-06 AD, and crossed the bridge Silsako.

And this accounts for the good state of preservation in which it find it in the present day; for with the exception of the masonry of the abutment at each end, in which large trees have taken root and displaced the stones, the rest of the structure may be said to be entire.

Several frieze-carved blocks are also lying near the end abutment from which I imagine the entrance of each may have been ornamented or these may have been gateways."

"The design and style of architecture of this bridge evidently belongs to a remote period in the annals of Kamrup and, in its original structure at least, must be co-eval with the erection of the ancient Brahmanical temples the remains of which are found so widely scattered throughout the length and breadth of Assam; the works of its former Brahmanical kings, a race long ago extinct in the annals of modem Hinduism and of whom the present race in Assam know nothing
