The obelisk at Prague Castle, a granite monolith and World War I memorial designed ...

... by Jože Plečnik, in front of St. Vitus Cathedral. It stands 16 meters high. The obelisk was donated by Tomas Garrigue Masaryk, first Czechoslovak president. It was erected in late 1928 to mark the tenth anniversary of the establishment of the First Czechoslovak Republic. The obelisk was originally to have been much larger, but while it was being transported to its intended location in 1928, it broke in two, and only part could be salvaged.
