Pindar is also the name of a military citadel under London.

The most important military citadel in central London is Pindar, or the Defence Crisis Management Centre. The bunker is deep beneath the Ministry of Defence on Whitehall. Construction took ten years and cost £126.3 million. Pindar became operational in 1992, two years before construction was complete. Computer equipment was much more expensive to install than originally estimated as there was very little physical access to the site.
