What’s your favourite outdoor sculpture? Louise Bourgeois’ giant spider, Maman, located outside the Guggenheim Bilbao, is one of our top contenders. Measuring over 30 feet high and 33 feet wide, the vast, eight-legged creature is made from cast bronze and bears a sac containing thirty-two marble eggs. Spiders regularly feature in the late French-American artist’s oeuvre as symbols of her mother Josephine, who passed away when Bourgeois was 21. Like the spider, Josephine was a weaver, the artist explained of the connection, as well as being similarly “clever… helpful and protective.”
