It is in Amsterdam's central Dutch capital to commemorate all homosexuals and lesbians who have been persecuted, and to see many locals and foreigners sitting by the water reading tablets, lighting candles and leaving flowers.
After searching for a long time, I haven't seen it many times, because these three flat triangles are so inconspicuous. In fact, this is just like the survival of sexual minorities, they are in the crowd, many times you can not see their existence. But in Amsterdam, where the streets are full of rainbow flags, they may really be able to live in the sun.
