Are my neighbours in quarantine?

I wondered for almost three weeks what this building opposite my place exactly was. It looks like an old prison somehow, but I have often observed taxis stopping in front of it, dropping off elderly women or people just like you and me. The mysterious gate is then opened and the visitors are welcomed by people in military uniforms. Could it be an army camp? But would Irish soldiers be visited by their grannies so often? Are all Irish soldiers softies? Oh my God - the sign said "Sarsfield Barracks". They could not mean "SARS-field", could they? Was I neighbour to thousands of infected people locked up behind barbwire?! Was this the reason why I was here one of about 15 students in a building set up for hundreds?
Don't worry about me :-). By now I have also come across Sarsfield Bridge and Sarsfield Statue, which has convinced me that I should do some research and stop speculating. Apparently, Patrick Sarsfield was an important miliary figure here in Limerick, which suggests that my neighbours are no patients but mere milksops. What a relief!

PS: There is a new quiz and a new quote.
