1 New water for New York City (1905)

It was 1905, New York City had more than 5,000,000 inhabitants and its population continued to grow annually by 150,000. The great Apple was taking its shape. Foreign and visitors started their voyage to the great city. But rain was scarce, and the diminishing water of the deposits came to a serious down point. Lack of water could not be afford in New York City. Growing industry and its people required new sources. The closest place to get water at the amounts needed was in the mountains of Catskill, some one hundred and seventy kilometres away and on the other side of the Hudson river. Thousands of workers began the constructions, it took 7 years for them to bring new water into New York City. Lands was bought for the deposit and obstacles where removed. Seven towns with a total of 2000 inhabitants where relocated and the towns vanished. Thirty two cemeteries where moved and 18 kilometres of railroad tracks where moved and placed elsewhere. A new lake took its place. A great dam for the time was built in crossing the creek Esopus Creek. This great dam was not entirely built of stones but has a nucleus of concrete and earth.

2 The crisis of the Renaissance (XIV-XVI)

The Renaissance occurred from the XIV to XVI Century. They are often remembered as glorious periods of the greatest human expressions, linked today with happy times. From Dante Alighieri, to Boccaccio Giotto and Franco Angelico or Leonardo Da Vinci the Renaissance is considered times of great expression, science and arts. The rebirth of new life and deep studies. However, these times where times of great conflicts in politics, society and economy. There where great suffering, conflicts and sadness. The power of the Church had diminished and politics was witnessing the demand of the new private tows that aspire for freedom. Lords aspired to transform certain areas and they surrounded themselves with mercenary soldiers. These mercenary soldiers fought relentlessly throughout the period, while the artistic propaganda carried out it's own silent and peaceful revolution.
