Wanderlust World Wanderlust World London, England is situated in the southeastern quadrant of the island of Great Britain, straddling the River Thames approximately 80 km (50 miles) from its North Sea estuary. This position—tidal river access deep inland, defensible hills (Ludgate, Cornhill, Tower Hill), and bridging point for north-south land routes—determined its 2,000-year trajectory from Roman Londinium to global metropolis.
