The same way the world settle its 7 wonders in history and the same number in modern times, Cuba counts on unique monumental works due to their technical solutions and magnitude.

The so called wonders of the Cuban civil engineering, a total of 37 proposals, encompass a period of 72 years with the first of them in the XIX Century.

This honour is given to the aqueduct designed by Francisco de Albear that began to function in 1893 and now a days is supplies 20%of the water to Havana City, with a delivery of 144 thousand cubic litres a day.

It was considered a master piece at its time and it was internationally recognized in Philadelphia and Paris fairs.

The second wonder was born on April, 1912; the “Havana City Culvert Tunnel” designed to evacuate the sewer waters by gravity and under the bay.

To 1931 the 1139 km of the Central Road from Occident to Orient of the Island were included in the list of privileged engineering works, with a building rhythm of 23.5 km per month. In 1956 the Focsa building joined the list for being one of the most important ones of its time with 39 floors at a height of 121 metres over the street level.

It has an underground parking lot for 500 cars, 375 apartments, shops and swimming pool together with 35 000 cubic metres of concrete, 120 km of cable pipelines and 1 million foot of copper wire used in its construction and no cranes were used to build it.

Two years after the construction of that monumental work began to function the Havana’s Bay Tunnel which allows passing under the Bay and eases communication between the city and its east part. The tubes that form the viaduct are from 12 to 14 metres under the sea, with 4 ruts that allow the traffic of about 6 000 vehicles per hour.

Another wonder is the Bacunayagua Bridge with heights even of 110 metres. For the first time in Cuba the structural concrete and the laminated steel for the semi arcs were used and it counts on 47 tone beams.

The most recent one is in the oriental part of the island and it is called the La Farola Viaduct that links Guantanamo and Baracoa with heights even of 450 metres over the sea level and as it was made in an ecological formation pneumatic hammers were used instead of explosives.
