An interesting monument which quickly became a popular sight of the city, even though it was installed only in 2005. In fact, it is a very popular selfie spot and one of the most often photographed places in Amsterdam.
The I amsterdam Letters can be found behind the Rijksmuseum, in the city centre. Another set of the letters welcomes the arriving people at the Amsterdam Airport. The last set of the letters appears in the city (changing spots quite often) whenever there is some occasion for it (festivals, fairs etc).
You can climb the letters but the monument is about two meters high so don't be surprised. Since the letters are so popular, there are many people every day.
