Castle Hill is free and open to the public to view; however, if an artist wishes to add their own flavor to the wall, they must obtain permission first.
Many graffiti purists think this caveat detracts from the true spirit of graffiti as an art form, while other artists are just happy to have place where the form can be celebrated without fear of legal ramifications.
Either way, Castle Hill is utterly unique and its work is constantly changing. A definite must see for locals and tourists alike.
