Archaeologists find wreck of large medieval boat in Barcelona

Experts hope vessel's old timbers and nails will help shed light on how boats were built during medieval period

Archaeologists excavating the site of a former fish market in Barcelona have uncovered the remains of a large medieval boat that was swallowed by the waters off the Catalan capital 500 or 600 years ago.

The area, which is being dug up in order to build a new centre dedicated to biomedicine and biodiversity, has already yielded finds ranging from a Spanish civil war air-raid shelter to traces of the old market and of the city's 18th-century history.
