Gluek Riverside Park is the site of the former Gluek brewery, which opened in 1857. The brewery was demolished in 1970 and this land was acquired by the Minneapolis Park Board eight years later. The park was closed in 2004 because of concerns over contamination from the longtime industrial use at this site. The park was finally reopened after several years being neglected and becoming very overgrown. Now this block is often lined, especially weekend nights, with cars bringing people to visit the two neighboring restaurants. Enjoy the benches, rivers overlooks, or even the picnic pavilion during your visit. On the plaque there is a four digit number, ABCD. Subtract AD from the North and add BC to the West to reach the final. Use stealth and carefully retrieve and replace the final. Happy Caching!
