It was in 1618 that the head of explorer and cartographer sir Walter Raleigh was chopped off, after a second and unsuccessful attempt to get to El Dorado. This happened at the Palace of Whitehall, which was at that time the main residence of the English monarchs in London.
The main reason was that Raleigh attacked areas which were clamied by the Spanish. The Spanish embassador lobbied to get Raleigh executed.
His body was to be buried in the local church in Beddington, Surrey, the home of Lady Raleigh, but finally laid to rest in St. Margaret's, Westminster, where his tomb may still be visited today.
