WThe Ann W. Richards Congress Avenue Bridge crosses over Lady Bird Lake in Austin, Texas. Before construction of the Longhorn Dam was completed in 1960, the bridge crossed the Colorado River from which Lady Bird Lake is impounded. The bridge was known as the Congress Avenue Bridge from the construction of the first span across the Colorado River at that location in the late 19th century until November 16, 2006, when the Austin City Council renamed the current bridge in honor of Ann W. Richards, the 45th Governor of Texas and a long-term resident of Austin. The bridge is a concrete arch bridge with three southbound and three northbound vehicle lanes and sidewalks on both sides of the bridge.

WA nest box, also spelled nestbox, is a man-made enclosure provided for animals to nest in. Nest boxes are most frequently utilized for birds, in which case they are also called birdhouses or a birdbox/bird box, but some mammalian species such as bats may also use them. Placing nestboxes or roosting boxes may also be used to help maintain populations of particular species in an area. The modern nest box was invented by the British conservationist Charles Waterton in the early 19th century to encourage more birdlife and wildfowl on the nature reserve he set up on his estate.
WBeer Quarry Caves is a man-made limestone underground complex located about a mile west of the village of Beer, Devon, and the main source in England for beer stone. The tunnels resulted from 2,000 years of quarrying beer stone, which was particularly favoured for cathedral and church features such as door and window surrounds because of its colour and workability for carving. Stone from the quarry was used in the construction of several of southern England's ancient cathedrals and a number of other important buildings as well as for many town and village churches, and for some buildings in the United States. Extraction was particularly intense during the Middle Ages, but continued until the 1920s. An adit to another set of workings can be seen from the South West Coast Path east of Branscombe, having been exposed by a landslip in the late 18th century. The quarry is part of the Jurassic Coast, and is a Site of Special Scientific Interest (SSSI).

WThe Green Grotto Caves are show caves and a prominent tourist attraction on the north coast of Jamaica.

The innermost cavern contains a crystal-clear underground lake.
WThe Hygieostatic Bat Roost is located in Kendall County, approximately 1.5 miles (2.4 km) east of Comfort on the south side of RM 473, in the U.S. state of Texas. It was erected in 1918 on property owned by former San Antonio Mayor Pro Tem Albert Steves, who had commissioned San Antonio health officer Dr. Charles A. R. Campbell to design the structure. The shingled pyramid-shaped raised tower stands 30 feet (9.1 m) high. One dormer serves as an entrance for the bats, while the other dormers are ornamental. The lower portion of the tower allows access for humans. The concrete base of the tower is raised 7 feet (2.1 m) off the ground, facilitating wagons being driven beneath to collect the guano.
