| | Re: Definite article "the" with places/buildings
Normally, when a place name starts with the name of a person - eg John Hopkins University - or of a place - eg Lancaster University - the article is omitted. on the other hand, if it starts with the noun (or adjective/noun) and/or includes the noun plus "of" - eg the University of Lancaster - it is included.
So normal usage would be :
Kazimierz Wielki Primary School in Przedbórz
John Paul II Junior High School in Przedbórz
Saint Paul's Cathedral
John Hopkins University
The Folk Museum in Przedbórz
The Church of Saint Alex in Przedbórz
The Johns Hopkins School of Medicine
If you follow these rules, you'll always be correct, even if certain institutions do break them idiosyncratically.
