Lisbon, the capital and principal seaport of Portugal, is situated on the right bank of the Tagus, 9 miles from its mouth. The town boasts of fine buildings - including the palace of Ajuda, the castle of St. George, the cathedral, custom-house, church of St. Coracao de Jesus - several of which are near the principal square, the Praca de Commercio. It also has scientific and literary institutions and a fine harbour, but the marvel of Lisbon is the marble aqueduct which brings the water more than ten miles across the valley of Alcantara. The exports are wine, oil, and fruit: the imports cotton, sugar, grain, coal, etc. The manufactures include tobacco, soap, wool, and chemicals. On November 1st, 1755, 30,000 inhabitants were destroyed by an earthquake, which wrecked the western half of the city and caused the fall of almost all the large public buildings and churches and convents.
