The London Eye, also known as the Millennium Wheel, is an observation wheel in London, England. At the time it was erected the largest/tallest observation wheel in the world, although there are now larger wheels, such as The Star of Nanchang, which was opened in May 2006. The London Eye stands 135 metres (443 ft) high on the western end of Jubilee Gardens, on the South Bank of the River Thames in London, England, between Westminster Bridge and Hungerford Bridge.

The Roman Baths complex is a site of historical interest in the English city of Bath. The complex is a very well-preserved Roman site of public bathing. The Roman Baths themselves are below the modern street level and has four main features, the Sacred Spring, the Roman Temple, the Roman Bath House and the Museum holding finds from Roman Bath. The buildings above street level date from the 19th century. Visitors can see the Baths and Museum but cannot enter the water. The water which bubbles up from the ground at Bath, fell as rain on the Mendip Hills. It percolates down through limestone aquifers to a depth of between 2,700 metres (8,858 ft) and 4,300 metres (14,108 ft) metres where geothermal energy raises the water temperature to between 64 °C (147.2 °F) and 96 °C (204.8 °F). Under pressure, the heated water rises to the surface along fissures and faults in the limestone. Roman_Bath_1 Roman_Bath_2

Stonehenge is a prehistoric monument located in the English county of Wiltshire, about 8 miles (13 km) north of Salisbury. One of the most famous prehistoric sites in the world, Stonehenge is composed of earthworks surrounding a circular setting of large standing stones. Archaeologists believe that the standing stones were erected around 2200 BC and the surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. The Stonehenge complex was built in several construction phases spanning at least 3000 years, although there is evidence for activity both before and afterwards on the site, perhaps extending its time frame to 6500 years.  Even though the last known construction of Stonehenge was about 1600 BC, and the last known usage of it was during the Iron Age (if not as late as the 7th century), where Roman coins, prehistoric pottery, an unusual bone point and a skeleton of a young male (780-410 cal BC) were found, we have no idea if Stonehenge was in continuous use or exactly how it was used.

Her Majesty's Royal Palace and Fortress, more commonly known as the Tower of London (and historically simply as The Tower), is a historic monument in central London, on the north bank of the River Thames. The Tower of London is often identified with the White Tower, the original stark square fortress built by William the Conqueror in 1078. However, the tower as a whole is a complex of several buildings set within two concentric rings of defensive walls and a moat. The tower's primary function was a fortress, a royal palace, and a prison (particularly for high status and royal prisoners, such as the Princes in the Tower and the future Queen Elizabeth I). This last use has led to the phrase "sent to the Tower" (meaning "imprisoned"). It has also served as a place of execution and torture, an armoury, a treasury, a zoo, the Royal Mint, a public records office, an observatory, and since 1303, the home of the Crown Jewels of the United Kingdom.
