The location: Located near the equatorial line in the northeastern coast of Brazil, Fortaleza, the capital of the state of Ceara', lies by the beach between the Ceara' and the Coco' rivers, in the middle of 570km (360mi) of sandy beaches of the State's coast. The hightest point in the city is only 30m (100ft) high and its beach front is formed of sand dunes up to 10m high and coconut trees. The weather is dry and sunny. A permanent breeze comes from the ocean and keeps the air clean and healthy while the temperature rests on a nice level year around. The lack of rain during most of the year, now a blessing for the visitors, prevented a definitive settlement in the area of Fortaleza until the middle of the 17th century. At that time, need to assure the hold of the land, the Portuguese established the "Fortaleza de Nossa Senhora da Assuncao" in the same place where a hundred years before the dutch had built the Schoonenbroch Fort. Fortaleza, named after the fortress, has been since then an important trading center and an artistic and cultural center of the country.
