disturbing. The concrete blocks offer no detail or reference to the Holocaust. The title of the monument does not include the words "Holocaust" or "Shoah". Critics have raised questions about the memorial's lack of information. "It doesn't say anything about who did the murdering or whythere's nothing along the lines of 'by Germany under Hitler's regime,' and the vagueness is disturbing". The question of the dedication of the memorial is even more powerful. "In its radical refusal of the inherited iconography of remembrance, Berlin's field of stones also forgoes any statement about its own reason for existence. The installation gives no indication who is to be remembered. There are no inscriptions. One seeks in vain for the names of the murdered, for Stars of David or other Jewish symbols".

Indeed, swastikas were drawn on the stelae on five occasions in its first year. In 2009, swastikas and anti-Semitic slogans were found on 12 of the 2,700 gray stone slabs. In 2014, the German government promised to strengthen security at the memorial after a video published on the Internet showed a man urinating and people launching fireworks from its grey concrete structure on New Year's Eve. The monument is often used as a recreational space, inciting anger from those who see the playful use of the space as a desecration of the memorial. According to architecture critic Nicolai Ouroussoff, "The day I
