Zugló is Budapest's second greenest district. Zugló has recently been undergoing a residential development, because it's become a very popular target for citizens planning to buy an apartment. You can buy a nice flat in green surroundings here, similar to those in the Buda Hills, for less money. Attractions include Heroes' Square with the grandiose Millennium Monument, Budapest Zoo, the Botanical Gardens and the Amusement Park in City Park (Városliget).
