Until quite recently a great many mages lived near Novigrad's main square. They fled when the witch hunters began their reign of terror, leaving many of the city's most beautiful townhouses abandoned and uncared for.
|— In-game description|
Hierarch Square is one of the main squares of Novigrad. Many nobles live here, situated in front row seats to the regular executions of mages conducted by the witch hunters. The first time Geralt arrives here in The Witcher 3, he may witness the executions of sorceress Felicia Cori and of the doppler Chappelle.The square is littered with trading posts and market stalls, much like the nearby Fish Market. It hosts several merchants, including a herbalist, and an armorer in an alcove beneath one of the buildings on the western side. One of the merchants possesses sizeable amounts of mandrake cordial and cherry cordial - two of the ingredients required for making white gull which is used in many higher-level alchemical recipes.
Triss' ransacked house can be accessed through a gate on the south side of the square.
