In the popular mind, the history of Hong Kong, long the entryway to China for Westerners, begins in 1841 with the British occupation of the territory. However, it would be wrong to dismiss the long history of the region itself. Archaeologists today are working to uncover Hong Kong's past, which stretches back thousands of years. You can get a glimpse into that past at Lei Cheng Uk Museum's 1,600-year-old burial vault on the mainland just north of Kowloon. In 1992, when construction of the airport on Chek Lap Kok was begun, a 2,000-year-old village, Pak Mong, was discovered, complete with artifacts that indicated a sophisticated rural society. An even older Stone Age site was discovered on Lamma Island in 1996. While Hong Kong remained a relative backwater in early days, nearby Guangzhou (Canton) was developing into a great trading city with connections in India and the Middle East. By a.d. 900, the Hong Kong islands had become a lair for pirates preying on the shipping in the Pearl River Delta and causing a major headache for burgeoning Guangzhou; small bands of pirates were still operating into the early years of the 20th century. In the meantime, the mainland area was being settled by incomers, the "Five Great Clans": Tang, Hau, Pang, Liu, and Man. First to arrive was the Tang clan, which established a number of walled villages in the New Territories that still exist today. You can visit Kat Hing Wai and Lo Wai, villages with their walls still intact. Adjacent to Lo Wai is the Tang Chung Ling Ancestral Hall, built in the 16th century, which is still the center of clan activities. The first Europeans to arrive in the Pearl River Delta were the Portuguese, who settled in Macau in 1557 and for several centuries had a monopoly on trade between Asia, Europe, and South America. As Macau developed into the greatest port in the East, it also became a base for Jesuit missionaries; it was later a haven for persecuted Japanese Christians. While Christianity was not a great success in China, it made local headway, evidenced today by the numerous Catholic churches in Macau's historic center. Intermarriage with the local Chinese created a community of Macanese, whose culture can still be seen in Macau's architecture and cuisine. <sep>Why did traders from Canton have problems in the Pearl River Delta?<sep>Because the water was too shallow

For much of the world, the Algarve is synonymous with Portugal, yet the Portuguese will tell you the exact opposite: the region has little in common with the rest of the country. The southern stretch of coast is more reminiscent of a North African landscape than a European one. It has no cosmopolitan cities, like Lisbon and Porto, which are farther north. Most of Portugal is known for quaint towns, medieval castles, and grand palaces. The Algarve is more recognizable for impenetrable blocks of tourist apartments, hotels, and meticulously manicured golf courses. And beaches. Think Algarve and the mind pictures long, glorious stretches of golden sands, secluded coves framed by odd ochre-colored rock formations, and deep green waters. With about 160 km (100 miles) of coastline, Portugal's southern province is one of Europe's premier beach destinations. The occasionally chilly ocean is the Atlantic, but the Algarve has a sultry Mediterranean feel. Its consistent climate is the best in Portugal, and one of the kindest in the world: more than 250 days of sunshine a yearmore than almost any other international resort area. The moderating effect of the Gulf Stream produces a fresh springtime breeze throughout winter, and in late January and February, white almond blossoms blanket the fields. In summer the heat is intense but rarely unbearable, and regardless, beautiful beaches and innumerable pools are always just a dive away. Magnificent year-round weather has made the Algarve a huge destination for sporting vacations. Superb golf facilities aboundseveral with tees dramatically clinging to cliffs and fairways just skirting the edge of the oceanand horseback riding, tennis, big-game fishing, sailing, and windsurfing are immensely popular. Sports, beaches and hospitable weathernot to mention easily organized package vacationsare surely the reasons the Algarve receives as many visitors as the rest of Portugal in its entirety. But it's not just international tourists that descend on the Algarve; many Portuguese from Lisbon and elsewhere in the north have holiday homes and spend their summer vacations here. The coast is neatly divided into the rugged Barlavento to the west and the flat beauty of Sotavento to the east. West is where you'll find the famous orange cliffs and surreal eroded rock stacks. <sep>Which division of the Algarve coast has the orange cliffs and rock stacks?<sep>North
