Lisbon is a lively, international city which lies on seven low hills at the estuary of the River Tagus. In the centre of the city is the medieval castle of Sao Jorge, which stands with its ten towers as it did back in the Phoenician times. The beach resort of Estoril is a few miles from the capital, so for anyone with time on their hands could take a day trip to this most pretty coastlines of Portugal along with seeing the Formula One Grand Prix (if you are there at the right time). ,Once at the heart of the greatest seafaring nation in the world, Lisbon nowadays still has an air of majesty that transcends time.
