When the roof of St. George’s Church in the Czech Republic caved in during a 1968 funeral, it was the last straw for those who thought it was haunted. The old, decaying building was abandoned for years until an artist filled it with ghost sculptures. Enough people visited the ‘ghost church’ that the congregation was able to use donations to fix the structure, and they now hold services amid the ghosts. Source

“The weather project” of 2003, which drew more than two million visitors to the Turbine Hall of Tate Modern

Olafur Eliasson on How to Do Good Art

Eliasson was born in Copenhagen to Icelandic parents in 1967. His most celebrated work to date is 2003’s “The weather project,” for which the Turbine Hall of London’s Tate Modern was converted into a gigantic, artificial solarium, attracting over the course of six months two million visitors, who often felt compelled to lie down on the floor, spelling out political messages with their bodies or just gazing at themselves and each other in the mirror on the ceiling. My own favorite work of Eliasson’s is “Your waste of time,” an installation at MoMA PS1 in Long Island City last year that consisted of several chunks of ice, detached by seasonal melting from an Icelandic glacier, that had been fished out of a lake, shipped to New York and installed in the refrigerated gallery. There they sat for nearly four months, crystalline but also surprisingly grimy, stout as rock but also frail enough to need their own microclimate — individual and real and lost.

Once a year muggle parents and siblings are allowed to visit Hogwarts to see where their daughters/sons/brothers/sisters go for most the year. Each visitor is given a specially charmed bracelet that stops the muggle-repellent wards affecting them. The bracelets also let them access other wizarding spaces such as Diagon Alley and Platform 9 ¾.
