We would have needed a block and tackle to get a harpsichord up there. The architect did not anticipate organ technicians. As far as I can remember the route, you had to go up in the rear balcony of the main sanctuary and unlock a little door in the panelling on the south wall. This led into the organ loft at the rear of Mikell Chapel. A door on the OTHER side of the little organ loft led out onto the roof under the flying buttresses. You walked along that roof to the south transept, where there was a ladder up the west wall of the transept to THAT roof. A second ladder led up to a door in the south wall of the base of the tower. That put you up in the roof above the ceiling of the crossing. I'm a little fuzzy where we went after that, but somewhere a catwalk led to another ladder and a trap door into the lowest tower room. There were three ladders and three successive rooms, and a final caged ladder led out into a little stairhouse on the tower roof. I'm not sure how tall the tower is, but you get a great view of downtown.
