Goes overseas often to take in a lot of historic and curious buildings (7)
I believe the answer is:
follies
'curious buildings' is the definition.
(folly can mean a purely ornamental structure)
'goes overseas often to take in a lot of historic' is the wordplay.
'goes overseas often' becomes 'flies' (as in flying overseas regularly).
'to take in' means one lot of letters goes inside another.
'a lot of' means to remove the last letter (most of the word but not all of it).
'historic' becomes 'old' (I've seen this in another clue).
'old' with its final letter removed is 'ol'.
'flies' placed around 'ol' is 'FOLLIES'.
'and' is the link.
(Other definitions for follies that I've seen before include "Ornamental buildings with no practical purpose" , "Rash actions" , "Idiocies" , "Silly acts or ornamental buildings" .)
