Visiting the old city streets and shops in Lagos by dlytle
Access to the old town is easy through entrances in the wall. The main shopping and tourist area is closed to vehicles, so you can browse and take in the sights at your leisure. Once inside, you'll find a market and neat, well-supplied shops specializing in silver filigree, copper, leather, a good selection of wines, great breads and delicious pastries. There is also a wide variety of restaurants for all tastes. The great earthquake destroyed or damaged many of the historic buildings, but left unscathed one that you absolutely should not miss. It's one of Portugal's national treasures, the military chapel of Santo Antonio.
