Venice officials have introduced a raft of new rules for tourists, including rules against littering, swimming in canals and walking the streets shirtless.
And the crackdown on badly-behaved tourists has been taken very seriously by officials, who slapped two German visitors with a fine and ordered them to leave Venice under the decree known locally as a "Daspo".
Lonely Planet report two backpackers from Berlin got out a stove and started to make a themselves a coffee at the foot of the Rialto Bridge - the oldest of the four bridges on Venice's Grand canal.
A passer-by reported them to police and they were fined €950 ($1058) for unseemly behaviour and told to leave Venice.
But far from it being a one-off, officials say it was the 40th time since May that tourists were ordered out of Venice for rule-breaking.
So, what are the rules?
The rules state you should walk on the right, should not stand at any time on bridges, and don't lead bikes by hand.
You cannot set up a picnic on steps of churches, bridges, wells, monuments and banks of streams, canals etc.
Officials say St. Mark's Square is a monumental site and excluding pertinent bars and restaurants, it is forbidden to stand at any time in order to consume food or drink.
It is forbidden to camp, walk about in swimwear, dive and swim in canals.
They say: "Respect the environment and artistic wealth: do not litter, do not vandalize with graffiti, or padlocks. Do not give food to the pigeons.
They also urge tourists to try to visit Venice when it is less crowded.
Drinking alcohol on the street is not allowed between 8pm and 8am.
Fines range from €25 to €500.
Last December, the city got approval to introduce a tourism tax to target daytrippers, which is likely to come into force later this year, according to the Mirror.
The €10 (£9) is aimed at short-stay tourists like cruise ship visitors, who are viewed as swelling the city's crowds but contributing little to the economy.
Tourists who dodge paying the fee will be able to be slapped with a fine of up to €450 (£406).
