Went first as well round Spanish city (6)
I believe the answer is:
toledo
'spanish city' is the definition.
(I've seen this before)
'went first as well round' is the wordplay.
'went first' becomes 'led'.
'as well' becomes 'too' ('too' can be a synonym of 'as well').
'round' indicates putting letters inside.
'led' going inside 'too' is 'TOLEDO'.
(Other definitions for toledo that I've seen before include "Tapering sword" , "Spanish city, famous for steel and swords" , "Looted the Spanish city badly" , "Covering, hiding" , "Spanish city famed for swords" .)
