An eyesore is something that is largely considered to look unpleasant or ugly. Its technical usage is as an alternative perspective to the notion of landmark. Common examples include dilapidated buildings, graffiti, litter, polluted areas, and excessive commercial signage such as billboards. Some eyesores may be a matter of opinion such as controversial modern architecture (see also spite house), transmission towers or wind turbines. Natural eyesores include feces, mud and weeds.
In the USA, the National Association of Realtors says an eyesore can shave about 10% off the value of a nearby listing.
Clean-up programmes to improve or remove eyesores are often started by local bodies or even national governments. These are frequently called Operation Eyesore. High-profile international events such as the Olympic Games usually trigger such activity.
Others contend that it is best to nip such problems in the bud by addressing them while they are small, since signs of neglect encourage anti-social behaviour such as vandalism and fly-tipping. This strategy is known as fixing broken windows.
Whether some constructions are eyesores is a matter of opinion which may change over time. Landmarks are often called eyesores.

Lloyd's building – Situated in the City of London, this building was described as an oil refinery when it was opened in 1986 for having most of its facilities, stairways and AC on the outside. Some people still say this, although the building has become more popular and liked in the recent years.
Tour Montparnasse - lone skyscraper in the Montparnasse area of Paris, France. Its appearance mars the Paris urban landscape, and construction of skyscrapers have been banned in the city two years after its completion.

It is sometimes said that the view from the top is the most beautiful in Paris, because it is the only place from which the tower itself cannot be seen.
