The Pombaline Lower Town (called usually as Baixa) area covers about 235,620 square metres of central Lisbon. It is an elegant district, primarily constructed after the 1755 Lisbon earthquake. It takes its name from Sebastião José de Carvalho e Melo, the Prime Minister to Joseph I of Portugal from 1750 to 1777 and key figure of the Enlightenment in Portugal, who took the lead in ordering the rebuilding of Lisbon after the 1755 earthquake. The Marquis of Pombal imposed strict conditions on rebuilding the city, and the current grid pattern strongly differs from the organic streetplan that characterised the district before the Earthquake.
The Pombaline Baixa is one of the first examples of earthquake-resistant construction. Architectural models were tested by having troops march around them to simulate an earthquake. Notable features of Pombaline structures include the Pombaline cage, a symmetrical wood-lattice framework aimed at distributing earthquake force, and inter-terrace walls that are built higher than roof timbers to reduce fire contagion.
Today Baixa area has elegant squares, pedestrianized streets, cafes, and shops. Old tramcars, street performers, tiled Art Deco shopfronts, elaborately decorated pastry shops, and street vendors selling everything from flowers to souvenirs, all lend a special charm to the area.
Baixa was placed on Portugal's tentative list of potential World Heritage Sites in 2004.
References:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
