What is an example of caesura?

An example of caesura can be found in the lines from the prologue of Shakespeare’s Romeo and Juliet:

“Two households, // both alike in dignity,
In fair Verona, // where we lay our scene.”

Here, the commas after “households” and “Verona” create natural pauses, marking the caesurae. These pauses emphasize the words that precede them—the two families and the setting—directing the audience’s attention to key elements of the plot.
