A weird landscape of the concrete, fluorescent-coloured shipping navigation marker a few hundred metres out from the beach on the artificial pier, on 18th July 2016, on Paredao da Praia da Barra, at Barra, near Aveira, Portugal. Visible to shipping many miles from the coast, the marker aides vessels to find their route from the open sea and through the narrow channel into the industrial port of Aveiro.
