Den Haag has a lot of nice galleries, most of them well hidden. Lhgwr is one of my favorites and it’s just a few meters from Hollands Spoor Station. Lhgwr is short for Liefhertje en De Grote Witte Reus (Deardeer and The Big White Giant), this gallery is specialized in modern art, they often have (experimental) exhibitions with cool photography. One thing I really like about this place is their awesome store, they sell fashion items, nice decoration for your home, books, watches and jewelry. All unique pieces and the collection changes every once in a while. Make sure to pay them a visit now and then!
