Location of imperial lazaret?

Can someone tell me exactly where was the imperial lazaret that Alexandra and the Big Pair worked in during WWI? Am I correct that it was it the Catherine Palace lazaret? All I can recall at the moment is that it was within walking distance.

Also, where was the Little Pair's hospital?

Sarushka, to my knowledge Empress Alexandra opened many hospitlas/lazaret(s) across all Imperial Russia. She had map of lazarets in Russia.
So, in Evtarpia/Crimea she opened one lazaret in Spring of 1916. That event was filmed, I saw it.
Then, in St.Petersburg many lazarets were opened, at Catherine Palace, as you mentioned. then,there was feodorovsky lazret,which Little Pair visited oftenly.
Probably there are some more not famous as these two, like small hospitals near front at Stavka. Don't forget Empress Marie - but I totally forgot where she opened lazaret. I'll check. Olga Alexandrovna.
I have just found some pics. of MA's lazaret,Tsarskoe Selo:

I think Serge Essenin can be seen in that one. I read he was in MA's Lazaret, or even has been photographed in front of it. I'll look for more infos.

I found some locations of lazarets:

Императрица Александра Федоровна организовала особый эвакуационный пункт, куда входило 85 лазаретов для раненых воинов в Царском Селе, Павловске, Петергофе, Саблине и других местах.

Thanks to these things, gees!
