Broadway Tower is a folly located on Broadway Hill, near the village of Broadway, in the English county of Worcestershire, at the second highest point of the Cotswolds after Cleeve Hill. Broadway Tower's base is 1,024 feet (312 metres) above sea level. The tower itself stands 55 feet (17 metres) high. The “Saxon” tower was designed by James Wyatt in 1794 in the form of a castle, and built for Lady Coventry in 1799. The tower was built on a “beacon” hill, where beacons were lit on special occasions. Lady Coventry wondered if a beacon on this hill could be seen from her house in Worcester – approximately 22 miles (35 km) away – and sponsored the construction of the folly to find out. The beacon could be seen clearly.

The Atlantic Ocean Road or the Atlantic Road (Norwegian: Atlanterhavsveien) is a 8.3-kilometer (5.2 mi) long section of County Road 64 that runs through an archipelago in Eide and Averøy in Møre og Romsdal, Norway. It passes by Hustadvika, an unsheltered part of the Norwegian Sea, connecting the island of Averøy with the mainland and Romsdalshalvoya peninsula. It runs between the villages of Karvag on Averoy and Vevang in Eida. It is built on several small islands and skerries, which are connected by several causeways, viaducts and eight bridges – the most prominent being Storseisundet Bridge.

This is the hilarious moment a terrified baby hippo ran screaming for its mum when a flock of bird landed on its back in South Luangwa National Park in Zambia. The hippo was seen screaming, running and twisting from side to side in a desperate bid to shake off the red and yellow ox-pecker birds. Ox-peckers and hippos usually have a mutually beneficial relationship where the birds help free hippos of ticks and other parasites by feeding on them. (Photo by Marc Mol/Caters News/SIPA Press)
