The map portrays a floor plan of Teatro Grassi, specifically the stalls, located on floor -1 of the building.

Conventional signs

• The solid lines are walls;
• the checkered areas are the seats;
• the dashed rectangle outlines the stage;
• the multiple thin arrowheads are stairs and ramps;
• the filled raised surfaces are areas that are inaccessible to the general public or obstructions from structural elements;
• the dotted areas are the toilets; the cross marks the position of this panel. 
   

Exploration 
In the upper left corner of the map you will find the words “Teatro Grassi – Platea” (meaning “Stalls” in Italian) in large print and in braille, while in the upper right corner is the QR Code linking to this guide.

Now place both hands on the lower edge of the map and move your fingers slightly upward. You will find a thick solid line, running along roughly two-thirds of the lower edge of the panel. This is the perimeter wall of floor -1, interrupted by several markings: let us interpret them one by one. 

If we place our fingers on the lower right corner of the structure and slide them inward across the wall, we can identify a staircase represented by a coil of small arrowheads. These are arranged around the line of a wall forming a sort of right-angled “spiral”. This is one of the two staircases leading to the foyer on the ground floor; we find the other, symmetrical one, on the left side, beyond two vertical walls separated by a hollow space.

For the time being, let us return to the right-hand staircase and move our fingers slightly upward from the arrowheads. We will find a cross: this is where we are located in the stalls foyer. Moving slightly to the right from the cross we will find a gap in the vertical side of the building, representing an emergency exit.

Going back to the cross, and just above it, we can feel a raised square representing a pillar. By moving our fingers to the left, we will find three more pillars: the two middle ones are connected by a wall, whereas we will find openings between the outer and central pillars, which are the entrances to the stalls.

If we slide our hands upward from the pillars, we will find a large checkered surface occupying most of the central area of the panel. This is the stalls area, fenced at the top by a broken line outlining the raised proscenium. Just beyond this line, we find a dashed rectangle representing the stage area.

Continuing upward beyond the top of the stage, we will encounter a large irregular raised polygon. These are storage and service areas not accessible to the public. 

Let us now return to the lower part of the map and move to the left-hand staircase, which also leads to the ground floor. On its left side, we can feel a dotted area representing the toilets, which can be accessed from the corridor. Moving our fingers upward, we will find several horizontal walls dividing the different bathrooms. After passing the third and last one, let us follow the perimeter wall, which winds back vertically and presents an opening on the left side of the stalls: this opening is another emergency exit connecting the stalls to the outside.
