Galle Fort
If you are talking about fortified towns, nothing can beat the Dutch fort in Galle, which has the distinction of being the best-preserved sea fort in South East Asia. Also named as a world heritage site, you can still capture the essence of an old world charm, where the constricted streets are dotted with Dutch colonial villas. The most captivating building out of the lot would be the Dutch Reformed Church, including ornately carved memorials to the city's Dutch settlers. If you would like to be a part of this beautiful place, be attune to its colonial ambience, the fort hosts some of the island's fantastic boutique-style accommodation which are former villas restored to their colonial glory.
