Went around gallery protected by staff (7)
I believe the answer is:
rotated
'went around' is the definition.
('rotate' can be a synonym of 'go around')
'gallery protected by staff' is the wordplay.
'gallery' becomes 'tate' (I've seen this before).
'protected by' indicates putting letters inside.
'staff' becomes 'rod' (I've seen this before).
'tate' put inside 'rod' is 'ROTATED'.
(Other definitions for rotated that I've seen before include "Turner did?" , "Turned in a circle around an axis" , "Had spin" , "Turned around axis or central point" , "Revolved" .)
