This is the Princess Margaret Hospital, the medical facility in Funafuti.
I found a recent first hand, and really well written report of a traveller’s experience of getting sick and being treated at the hospital. It’s never fun getting sick while travelling, and I’m glad that I’ve never really been unlucky enough to come down with anything too drastic on my travels to different places. (Ah, there was that time after a night on the sakau in Pohnpei – I’d nearly forgotten about that…)
