I never heard of it but I am impressed. A good view of it.
and there is another close by.
The Two Towers in Lord of the Rings comes to mind.
The Pico Cão Grande (Portuguese for “Great Dog Peak”) is a landmark needle-shaped volcanic plug peak in São Tomé and Príncipe, in the Caué District of São Tomé Island in Parque Natural Obô de São Tomé. Its summit is 663 m (2,175 ft) above sea level, and it rises about 370 m (1,210 ft) over the surrounding terrain. The volcanic plug was formed by magma solidifying in the vent of an active volcano.
Volcanic Plug seems a dismissive term for something so grand.
