The Town Gate, called Landporten in Danish, is one of the surviving pieces of old Tranquebar's fortifications. The original gate belonged to the 17th-century Danish settlement; the present structure was rebuilt in 1791 after the earlier gate was destroyed.
It is a short stop, but it helps frame the colonial street plan around Fort Dansborg. Combine it with the fort and the old seafront buildings rather than making a special trip for the gate alone.
