The Eurovision Song Contest 2013 was held in Malmö, Sweden. The winner of the 2013 contest was Denmark, represented by Emmelie de Forestand the song "Only Teardrops". As Denmark won the competition, the Eurovision Song Contest 2014 will be held in the Danish capital of Copenhagen.
The Eurovision song contest in 2011 was won by Ell/Nikki. The song performed was "Running Scared" and was performed for Azerbaijan. The contest took place in Dusseldorf, Germany, as Germany won it the previous year.
I am not quite sure what you mean by "arranged". Bobbysocks won the Eurovision Song Contest in 1985 for Norway, but the contest was hosted by Sweden in Gothenburg, as Sweden had won the contest the previous year.
The Eurovision Song Contest was not in Ireland in 1996. Ireland won it in 1996, but the contest was held in the Oslo Spektrum in Oslo, the capital of Norway, as Norway had won the 1995 Eurovision Song Contest that was in the Point Theatre in Dublin.
