Part of the church in a pseudo Gothic style (4)
I believe the answer is:
apse
This clue could be a double definition.
'part' is the first definition.
(I have seen 'Part of church ' mean 'apse' so perhaps 'part' could also mean 'apse')
'church in a pseudo gothic style' is the second definition.
'apse' can be an answer for 'church' (I've seen this before). I'm unsure of the 'in a pseudo gothic style' bit.
'of the' is the link.
Can you help me to learn more?
(Other definitions for apse that I've seen before include "Large recess in church" , "Peas (anag) - found in church" , "Recess at east end of church" , "In sacred space" , "inside church?" .)
