There are great variations in terrain and climate among the historic provinces. Trás-os-Montes in the extreme northeast has a rigorous mountain climate, as have parts of Entre-Minho-e-Douro (officially Douro). Beira has the highest mountains of the country, the scenic Serra de Estrela, dotted with resorts. Estremadura, in W Portugal, has broad, alluvial plains, rising to cool and rocky uplands; along the Atlantic coast is a celebrated resort region, reaching to the town of Estoril, near Lisbon. Most of Alentejo has a Mediterranean climate; although much of its soil is poor, together with Estremadura it is the granary of Portugal. The southernmost of the old provinces, Algarve, resembles the northern shores of Africa; mountains curve across the north of the province down to Cape St. Vincent, the southwestern tip of Europe; citrus and almond groves and off-season vegetables thrive in the mild climate. In addition to the capital, other notable cities are Oporto, Coimbra, Setúbal, Braga, Évora, and Faro. The republic, including the island groups, is divided into 18 administrative districts, although the names of the six historic provinces are still used. Under a 1987 agreement, Portugal's last overseas territory, Macao, is scheduled to revert to Chinese sovereignty at the end of 1999. The majority of the Portuguese people are Roman Catholic. Portugal has several universities, including ones at Coimbra, Oporto, and Lisbon.
