Founded by Sir William Henry Gregory, the British governor of Ceylon during that time, the Colombo National Museum is a colonial type mansion heavily influenced by Italian architecture. It is Sri Lanka's oldest, largest and most prestigious museum. First opened to the public in January of 1877 with only 800 items on display, today that number has grown to an impressive 100,000. If you're an avid fan of history, the museum also maintains a library that hosts a vast collection of old and rare historical books and chronicles. The museum board is heavily involved in conducting research into prehistoric ethnology, culture, crafts and anthropology. It also conducts lectures and seminars for the public periodically.
