A great many hospitals are named “Memorial” something-or-other. I realize in general that this refers to naming the hospital “in memory” of someone (ie. a benefactor, etc), but the fact that so many hospitals have the word in their organization name but few other organizations do seems puzzling (why not JFK “Memorial” High School?). Am I just exercising extreme selective memory or have the hospitals acquired some kind of monopoly on the title?
There are lots of memorial stadiums and memorial parks (not including cemeteries).
Many memorial bridges, too.
Imagine your Uncle Bob died of frumious bandersnitis and left you piles of money in his will. In an effort to aid other people with bandersnitis, wouldn’t you be more likely to build an Uncle Bob Memorial Hospital with a big research wing than build an Uncle Bob Memorial Elementary School?
Schools get named after people, but it’s rarely the same kind of “in memorium” bequest. It’s more of an honorary thing.
What I don’t get are “memorial” names that don’t seem to be in memorial of any specific thing. For example, the name of the hospital in my hometown is “Brazosport Memorial Hospital.” “Brazosport” is the general name for the group of cities in that area, and it’s neither dead nor gone. So, why Brazosport Memorial?
That’s the only example I have on hand, but this kind of thing seems relatively common for hospitals.
Sometimes it’s in memory of the person who gave a pile of money to build the place. It seems every university in Indiana has a Krannert building. Sometimes, in the case of government buildings and bridges, it honors a dead person of the same party as the folks in power at the time. Oddly, federal court houses are sometimes named after living politicians. You just can’t hide your lionize. * 
Here in my town, one bridge is called the Eisenhower Bridge, after a dead Republican president. A few years later, after a change of local power, the next bridge was named the Truman Bridge, after a dead Democrat president. The one after that is called the Veterans’ Memorial Bridge.
*I’ve waited for years to use that. 
Yeah, well, B’port may not be dead and gone, but it certainly isn’t the garden spot of Texas. Not my favorite part of Texas.
My favorite strange use of “memorial” is in Austin. The home of the UT Longhorns is Darryl K. Royal Texas Memorial Stadium. Up until a few years ago, it was Texas Memorial Stadium, in honor of TexasExes who perished in World War I. (Their names are on plaques located around the original parts of the stadium.) Royal’s name was added during a recent renovation and expansion. The thing is, Royal ain’t dead. But there it is, Royal Memorial Stadium.
Take a look inside that Memorial Hospital. There may be many little memorials to people who have left money. A wing, a research lab, etc. may carry names of people.
