North Korea's 105-storey hotel had been abandoned since 1992, until Egyptian construction giant Orascom took on the project in 2008. How North Korea was ever able to build a supertall tower is baffling in itself, but this one is so ugly that even the government air brushes it out of tourist material.

Prague's Zizkov television tower earned its place in the top ten ugliest buildings compiled by online travel website Virtual Tourist last year, and it is easy to see why. Not only does the building tower above the Czech Republic capital's skyline like some sort of giant steel drill bit, but, bafflingly, it feaures statues of babies crawling towards the antennae like something out of a weird sci-fi movie. Finished in 1992, the Zizkov was built during the period of communist rule in Czechoslovakia, and was rumoured to be capable of blocking western radio and television transmissions. Nowadays the building is equally unpopular, and tower management try to attract visitors by stressing its techological innovations.

At first glance Bangkok's Chang Building is quite funny, but the novelty quickly wears off. It's a travesty of design in almost every way, but the worst bit is the fact that the designers went to the trouble of adding both an eye and an ear to the building.

To Kosovo now, and a building so ugly it doesn't even have its own Wikipedia page. This is the country's national library, and is rumored to be part of a national literacy drive - the thought was that making the national library this ugly would force people to go inside just to avoid looking at it.

It's always said that context is key when designing an iconic building, so it is little surprise that New Zealand's Beehive is so widely hated in the country. The building - which houses the executive wing of New Zealand's government - wouldn't be so bad if it was built on, say, a space station, but smack next door to Wellington's beautiful Edwardian Parliament House it looks a little out of place.

Money pit, anti-climax and ugly to boot,the Millennium Dome is most hated building in Britain - so vilified by the UK tabloids that they did everything short of going out there and burning it to the ground. Designed by architect Richard Rogers, the Dome now forms part of the O2 music venue in London.
