May 18 is the International Day of Museums. Since 1978, May 18 has been celebrated as International Museum Day in more than 150 countries, including Armenia. The preparations to this worldwide celebration start several days prior, when the all-European event “Museums at night” is held. Within the framework of this event, all the museums offer free entry till late night. In addition, numerous exhibitions and special events are being organized on that day. On May 16, the annual project “Museums at Night” kicked off with an event called “Museums: memory witnesses”. Thousands of citizens visited Yerevan museums this year. There were many young people among the visitors, for whom this is a real feast.
