The Sundarbans mangrove forest, one of the largest such forests in the world (140,000 ha), lies on the delta of the Ganges, Brahmaputra and Meghna rivers on the Bay of Bengal. It is adjacent to the border of India's Sundarbans World Heritage site inscribed in 1987.
The Castle of Otranto is a 1764 novel by Horace Walpole. It is generally regarded as the first gothic novel. In the second edition, Walpole applied the word 'Gothic' to the novel in the subtitle – 'A Gothic Story'. The novel merged medievalism and terror that has endured ever since. The aesthetics of the book shaped modern-day gothic books, films, art, music and the goth subculture.
Castle is sometimes used as a catch-all term for all kinds of fortifications and, as a result, has been misapplied in the technical sense. An example of this is Maiden Castle which, despite the name, is an Iron Age hill fort which had a very different origin and purpose.
