Extending to reach around 150 miles in length, the longest broken beach in the world is the Praia do Cassino Beach in Brazil. This is longer than the entire coastline of New York State (127 miles) or New Jersey State (130 miles). Length aside, this beautiful beach is known for its white sand, welcoming locals, and warm temperatures as well. Although the temperature here remains on the border of hot for most of the year, there are plenty of water activities that beach-goers can enjoy to help them cool off. Of these, surfing happens to be the most popular of them all. For a better perspective of its size, consider the fact that this beach is so long, it stretches all the way from the Rio Grande seaport to the mouth of the Chui stream adjacent to Uruguay.

The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China to protect the Chinese states and empires against the raids and invasions of the various nomadic groups of the Eurasian Steppe. Several walls were being built as early as the 7th century BC; these, later joined together and made bigger and stronger, are now collectively referred to as the Great Wall. Especially famous is the wall built 220–206 BC by Qin Shi Huang, the first Emperor of China. Little of that wall remains. Since then, the Great Wall has been rebuilt, maintained, and enhanced; the majority of the existing wall is from the Ming Dynasty (1368–1644).

The Grand Canal (also known as the Beijing-Hangzhou Grand Canal), a UNESCO World Heritage Site, is the longest canal or artificial river in the world and a famous tourist destination. Starting at Beijing, it passes through Tianjin and the provinces of Hebei, Shandong, Jiangsu and Zhejiang to the city of Hangzhou, linking the Yellow River and Yangtze River. The oldest parts of the canal date back to the 5th century BC, but the various sections were first connected during the Sui dynasty (581–618 AD). The Yuan and Ming dynasties significantly rebuilt the canal and altered its route to supply their capital Beijing.

The total length of the Grand Canal is 1,776 km (1,104 mi). Its greatest height is reached in the mountains of Shandong, at a summit of 42 m (138 ft). Ships in Chinese canals did not have trouble reaching higher elevations after the pound lock was invented in the 10th century, during the Song dynasty (960–1279), by the government official and engineer Qiao Weiyue. The canal has been admired by many throughout history including Japanese monk Ennin (794–864), Persian historian Rashid al-Din (1247–1318), Korean official Choe Bu (1454–1504), and Italian missionary Matteo Ricci (1552–1610).
