After two years of building work the newly refurbished Anne Frank museum in Amsterdam will be officially opened by king Willem-Alexander on November 22.

The building, in which the Frank family hid during the Nazi occupation until they were discovered in 1944, has been given a new entry area and more space for educational activities.

There will be more information about Anne Frank’s life, the eight other people who were hiding in the secret annex and the people who helped them. Audio tours in nine languages about the life and times of the young diarist will also be available.

The museum’s continued popularity – some 1.2 million people visit every year – necessitated the overhaul, the museum said.

The museum is not be open to the public on Thursday because of the royal visit but some 2,000 Amsterdammers will be given a free ticket for a visit on November 28 and 29.
