Tropical rainforest

-Tropical rainforest is one of the oldest types of vegetation to have survived and is found in an area that extends from Guinea, in the north, to the basin of the River Congo in the south. 

-the climate in the rainforest has high humidity and little seasonal variation. 

-Temperature is typically 30C by day and 20C at night.

-the combination of high rainfall it high temperature and humidity encourages the growth of a dense evergreen forest, where different species of trees grow to different heights. Above the thick undergrowth the canopy is formed by trees that may be 60 metres tall. 

-Historically the forest has provided food and material support for the indigenous people who live there.

-Colonialism has played a major role in this part of Africa and the three main types of colonial city are Portuguese, British and French.

-tropical rains dominate the climate in this region of Africa.

-There is architecture of fertility in this area, an architecture that has to deal with the climate and at the same time is responsive to the specific conditions in different places.

-The roof architecture of freetown is a good example of the language of form that is necessary to deal with the heavy rains.

-You can also see it in the architecture of Monrovia where you have over hanging roofs everywhere, if you go there in the rain, you understand why certain forms and details are used in such consistent way.

-The architecture of Accra is dominated by big roofs that protect the other building elements from the worst of the weather.
