Sacred place of frenzied Tuscan maidens (7)
I believe the answer is:
sanctum
'sacred place' is the definition.
(I've seen this before)
'frenzied tuscan maidens' is the wordplay.
'frenzied' is an anagram indicator.
'maidens' becomes 'm' (cricket abbreviation).
'tuscan' is an anagram of 'sanctu'.
'sanctu'+'m'='SANCTUM'
'of' acts as a link.
(Other definitions for sanctum that I've seen before include "Place of total privacy" , "Sacred or safe place" , "Private study" , "Inviolable retreat" , "Holy place, often inner" .)
