 A monument to Otto was built by the sculptor Max Unger in 1898 on the former Siegesallee (Victory Avenue) in Tiergarten in Berlin, as part of the construction of a "boulevard of splendor" with monuments from the history of Brandenburg and Berlin (with the commissioning by Emperor William II).Under the direction of Reinhold Begas between 1895 and 1901, 27 sculptors created 32 sculptures of the rulers of Brandenburg and Prussia, each 2.75 m (9 ft) high.Each sculpture was flanked by two smaller busts of people who played an important role in the life of that ruler.
