Tourists visit Ramnad to see the Raja Palace, which is still occupied by the Sethupaty Raja and his family to this day. Although no longer in power, the family contribute a great deal to the community by setting up schools and hospitals. They also welcome westerners to live in their palace who teach in their school through the Teaching and Projects Abroad organisation. One of them, the German Philip Radlanski who visited the royal family in late 2004 to contribute to their school as an English teacher, made a critically acclaimed documentary movie about the palace. Ramanathapuram is close to Rameshwaram, one of the main pilgrim centres in India. It is also close to Devipatinam which is another famous pilgrimage center in India.
