Take a trip to Galle Fort and it will be well worth your time. This masterpiece of a fort has been declared as UNESCO World Heritage Site for its "unique exposition of "an urban ensemble which illustrates the interaction of European architecture and South Asian traditions from the 16th to the 19th centuries." Even after an 400+ years, the fort is in excellent condition and a leisurely stroll along its cobbled streets would provide you with many diversions. There's quite a wonderful collection of vintage shops, restaurants and houses here, and almost all of them are built according to the colonial style of architecture. Both the Portuguese and the Dutch had heavy influence in Galle in the past, that even outside the walls of the fort, you can find many buildings built according to this style. These quaint old colonial buildings are so characteristic of the city, that many a Galle hotel in Sri Lanka such as the Tamarind Hill by Asia Leisure, were once the mansions of the colonizers.
