The recent T-list entry of the National Theatre of Guatemala apparently provides the wrong location. the coordinates point to the National Palace of Guatemala, built between 1939 and 1943.https://en.wikipedia.org/wiki/National_Palace_(Guatemala)
The T-list description starts with: "The National Theater of Guatemala is located in the Miguel Ángel Asturias Cultural Center, named in honor of the Guatemalan writer winner of the 1967 Nobel Prize in Literature."
The Miguel Ángel Asturias Cultural Centre was built in the 1970s by Efraín Recinos (this is mentioned later in the T-List description).
And Wikipedia says: "The Centro Cultural Miguel Ángel Asturias, commonly called Teatro Nacional...".https://en.wikipedia.org/wiki/Centro_Cultural_Miguel_%C3%81ngel_Asturias
A bit confusing, but the correct location should be: 14.627089, -90.517842
Yes, you are right, I had made the same remark to myself.
With the national palace it would have added a check mark for me (exterior), but not with this modern theater which I didn't even suspect existed!
