Trafaria is a small fishing harbour on the South bank of the Tagus. It is the last river port  before the sea.  Fishermen use small motor boats to place or bring in the nets that they leave overnight at the mouth of the river, or in the sea near the coast. There are always some of those  boats arriving or leaving. A huge silo was built by the water, and big cargo ships often stop there to be loaded with grain. It is not a tourist spot but it is a pleasant place to take a meal by the river. Seafood is excellent and the restaurants, although not very sophisticated, are very popular.
