Half-sunk in the harbour mud just south of the cruise pier, the rusting iron hull of the Lord Lonsdale is one of the more atmospheric sights in Punta Arenas. Built on the Mersey in 1889 as a four-masted barque, she was rounding Cape Horn in 1909 with a cargo of coal when fire broke out in the hold. The crew put in at Punta Arenas, the coal kept smouldering for weeks, and she was eventually condemned and abandoned in the bay.
For a century she has slowly slumped into the shallows, a ribbed iron skeleton at low tide. You can walk out along the coastal road south of the centre to see her up close. It's a useful reminder that for two and a half centuries this was one of the most dangerous stretches of water in the world.
