Exploration
In the upper left corner of the map you will find the words “Teatro Grassi – Foyer e Balconata” (meaning “Foyer and Balcony” 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 panel and follow the thick solid line tracing the perimeter of the building, running horizontally alongside the edge. Almost at the lower right corner, by moving our fingers upwards and crossing it, upon entering the building we will find a “B” in large print and in braille. This letter states that we are at the ticket office. To its left, a vertical line marks the counter separating it from the foyer and, directly above, a filled raised polygon stands in for a service staircase that is not accessible to the public.

If from the upper left corner of this polygon we move our fingers to the left, thus entering the foyer, we will soon find a cross: this marks the position of the panel, and this is where we are located. Immediately to its left we will find a broken line that represents one of the accesses to the “Nina Vinchi” Cloister, portrayed in another panel.

Just above this gap we will find a dotted shape: let us trace it with our fingers, and we will see that it forms an arrow, which indeed marks the main access to the foyer from the Cloister.

From this passage, let us follow the wall line to its left as it turns upward at a right angle, and not long after we will find the wavy line of a curtain draping a secondary access to the Cloister.

Let us now return to the lower right corner of the building, where the ticket office is, and move left following the thick perimeter line. About halfway across the panel, we will first meet a vertical line representing a short wall and, just beyond it, two groups of small arrowheads. These are one of the two staircases leading to floor -1, where the stalls are located.

Proceeding to the left we may notice an opening with a dotted arrow pointing downward. This is the main exit onto Via Rovello of Teatro Grassi. Let us proceed to the lower left corner of the map to find another staircase, mirroring the one we encountered earlier, marked by two more groups of arrowheads.

If from this corner we proceed upward along the perimeter wall of the theatre, which here is at a slight angle with respect to the panel edge, we will soon find a series of rooms in a dotted surface. These are the toilets, which can be reached from the foyer: indeed, there are a series of gaps along their right side corresponding to the doors.

From the upper left corner of the bathrooms, let us follow their upper wall toward the right and, after a small corner, move our fingers upward to find a gap in the building perimeter: this is an emergency exit that connects the balcony to the outside.

Now let us bring our hands back to the lower part of the panel, and more precisely to the horizontal section of the perimeter between the two staircases. If from here we scan upward, we should soon be able to recognise four raised squares. These are four pillars belonging to the wall, traced with a solid line, above which we will find the balcony.

Upward and past the wall we will identify a checkered surface representing the balcony seats. In between the various sectors, we may recognise the small arrowheads of two stairways running across them. To the right and left of these stairways, we will first find two smaller seating sections, and then we may identify two smooth corridors leading us back to the foyer.

Let us now return to the balcony. Proceeding upward, we will first find a raised surface which develops into a “U” or cup shape: this is where the balcony, bordered by a balustrade, opens onto the rest of the hall, located on floor -1 and portrayed in another panel. It appears here as a hollow area, flanked by two strips of checkered surface that represent additional balcony seating. The raised shape between the seating sections is a service lane closed to the public.

To the right and left of the balcony, as well as across the upper part of the panel just below the title, we will find irregular raised polygons: these are offices, workshops and other areas that are not usually accessible to the public.
