ANTWERP, Belgium (Reuters) - Archaeologists in Antwerp have spent the last two weeks excavating parts of a six-metre-high (20-foot) fortified wall that was built around the Belgian city 500 years ago.

The ruins were exposed during preparations for a massive infrastructure project on a major boulevard, including tunnels and a new tram line.
