Icelandic Penis Museum, be sure to visit Oslo. See the Viking Ship Museum, have dinner at the gay-friendly Cafe Christiana, and explore the four-story dark room-maze at the Saunahuset Hercules. But be sure to set aside a couple of hours for the Vigenland Sculpture Park, an 80-acre installation in Frogner Park on the north side of town.
It consists of 200 sculptures in bronze, granite, and wrought iron, life-sized or larger, created by Gustav Vigeland between 1939 and 1949. Not in isolation, like Borders in Dag Hammarskjold Park, they hug, touch, gaze at each other, displaying our journey from cradle to grave, and hopes for eternity. There are women and children, but mostly bald, muscular, naked men in homoerotic poses.
Here an older guy cruises a younger guy, or perhaps they're father and son.
A father seems to be swinging his son in the air. While they're both naked, of course.
There's also a museum with more of Vigeland's works, plus sculptures from many other Norwegian artists.
Not sure if Vigeland was gay or not, but he certainly preferred working with the male form.
He has been accused of being a Nazi sympathizer during World War II, but in fact he enjoyed the friendship and support of Jewish patrons.
