Yeah I think AJRC is correct.
When we mapped the Former T-list sites
we ended up with it as Hospital Real, Granada
. It was re added later as part of the 2007 updated t-list of Renaissance buildings of Granada, so seems possible and thanks to AJRC's link I can see it is also refred to as Hospital Real de la Santa Cruz.
The alternative is that the Hospital in Granada was based on the Hospital of Santa Cruz in Toledo
, however that would already be inscribed when this addition to the t-list was made in 1998 (infact I just saw that Toledo was originally propossed as just as the Hospital, which was news to me).
I think the one in Granada feels more correct to me, more so than Barcelona or Toledo.
