The phrase you’re looking for is almost certainly “Bridge of Sighs” , not “bridge of size.” It’s a famous historic bridge in Venice, Italy.

Quick Scoop

  • The Bridge of Sighs is in Venice, Italy.
  • It crosses a narrow canal called Rio di Palazzo.
  • It physically connects the Doge’s Palace (where trials and interrogations took place) to the New Prison (Prigioni Nuove).

What and where exactly is it?

  • City: Venice, in the Veneto region of northern Italy.
  • Location in the city: Between the Doge’s Palace and the New Prison, over the Rio di Palazzo, just off the main lagoon waterfront near St. Mark’s Square.
  • Material and look: An enclosed, white limestone bridge with small, barred windows along the sides.

Why is it called “Bridge of Sighs”?

The name comes from the idea that prisoners, crossing the enclosed bridge from the Doge’s Palace to the prison, would give a sigh as they caught their last view of Venice through the tiny windows before being locked up.

How to see it (if you visit Venice)

  • Most people view it from the nearby Bridge of Paglia , which sits along the waterfront just behind the Doge’s Palace and next to St. Mark’s Square.
  • You can also walk inside it as part of certain Doge’s Palace tour routes, which follow the same path prisoners once took.

TL;DR:
“Bridge of size” is almost certainly a misspelling or autocorrect of Bridge of Sighs ; it’s the enclosed white-stone bridge linking the Doge’s Palace to the New Prison over the Rio di Palazzo in Venice, Italy.
