Galleria Principe di Napoli Site Features

Count the arms. From inside, identify the three branches and the museum-facing portico; the missing fourth branch is explained by the church next door.

Use the stairs as evidence. The different stair lengths show how the gallery bridges the levels of Piazza Museo, Via Pessina and Via Broggia.

Look at the block, not only the roof. Residential buildings are integrated between the branches, so the gallery is a piece of mixed-use city rather than an isolated arcade.
