The Lourdes SIGINT (Signals Intelligence) facility, located near Havana, Cuba, was the largest facility of its kind operated by Soviet and later Russian foreign intelligence services[2] outside of Russia.

[3] All station facilities were shut down, the buildings were abandoned and later reconstructed to become the University of Information Science.

At its peak during the Cold War over 1,500 KGB, GRU, Cuban DGI, and Eastern Bloc technicians, engineers and intelligence operatives staffed the facility.

Russia had paid Cuba a $200 million annual subsidy from 1962 to 2002.

[4] In July 2014 reports surfaced that Russia and Cuba had agreed to reopen the facility for usage by Russian intelligence.
