Municipal authorities in the state of Pernambuco of Brazil are having serious problems due to coastal erosion. A number of artificial reefs have been built in the Ocean in front of the coast of Pernambuco and in front of Olinda as well.

The idea behind this approach is to attrack tourists and businessmen for a longer stay in Olinda and to offer them more than the historic scene of Olinda. The paper shows further the actions to be taken such as the extension of the reef till the shore, thus forming a lagoon with a guaranteed healthy swimming water conditions, but also how the infrastructure has to be changed necessary for the erection of new hotels fulfilling a performance that fits to the historic city of Olinda.
