History

It was built in 1953 on a rocky bluff named Morros dos Conventos nearby the beach.[2] The lighthouse is a cylindrical concrete tower with four buttresses surmounted by a metal skeletal tower with the lantern on the top. The tower is white painted with a black horizontal band. The light emits three white flashes, at 3.3 seconds interval, every twenty seconds visible up to 25 nautical miles (46 km; 29 mi). The lighthouse is managed by Brazilian Navy and is identified by the country code number BR-3960.

gollark: RPi4s can go up to, what, 2GHz at most? They have rather substantially worse IPC, too.
gollark: $30 for a cluster *and* peripherals? No.
gollark: Again, less so in perf/$.
gollark: Like I said, it isn't good for anything but learning clustering, since most stuff will not actually conveniently parallelize across devices and x86 systems offer more perf/$.
gollark: Clustered RPis aren't actually that good for much beyond cheaply learning clustering tech.
