The Tower to General John C. Frémont monument is located in Joaquin Miller Park, and was erected as a tribute to General Frémont by Joaquin Miller. On the spot of the monument General Frémont is thought to have stood and seen the San Francisco Bay for the first time, which he called the "Golden Gate." 1 There is some doubt as to whether Frémont was actually in Joaquin Miller Park, but it should be remembered that Miller was a poet, so perhaps it was poetic license.
On January 7, 1975, the Tower to General John C. Frémont was designated an Oakland Landmark, under Zoning Case #LM 74-335.
[ Including the modern spelling "Fremont" so searches will find it. ]
