This area is also in the grey ground castle area of the map. I don’t remember exactly where it is but it’s up the stairs of the castle but not quite at the top of the stairs by the warp gate since it’s facing the ocean.

The locations for these areee. The second one is a stamp location in the grey ground castle area of the map in the building to ur left from the entrance next to the warp gate at the top of the winding staircase. You get the first by jumping out the window and floating left onto the other balcony
