Madeira is a Portuguese autonomous archipelago (group of islands) in the north Atlantic Ocean. The Madeira Islands were accidentally rediscovered by Portuguese sailors who settled in 1418. Prior to that, the Islands had been referred to as Purple Island by the early Romans. Madeira and Porto Santo are the only two inhabited islands in this region. The islands are a year-round resort, known for the Madeira wine. Madiera Island has a population of approximately 245,000 people. The capital of the Madeira Islands is Funchal, which starts at the harbor and rises almost 1200m on gentle slope. Funchal is a modern city with over 104,000 residents, but traffic can be pretty bad; the city can be more readily observed by pedestrians. One of the most important sites is the cathedral built between 1493 and 1514. Madiera Island is the largest island of the group, its forests on the north slopes are designated as a UNESCO World Heritage Site. Visitors to the Madeira Islands will have an opportunity to see many native handicrafts for sale in area shops. Birdwatches will want to see the (or search for) the Zino's Petrel, Long-toed Pigeon and Madeira Firecrest, which can only be found on the Madeira Iland. In addition, a selection of breeding seabirds can also be observed.
