Of course - it's a British tradition :-)
On the dot of twelve noon each day, a canon shot sounds over central Nice. Look up to the sky and you will catch the puff of smoke from the explosive aerial charge. It is the canon of Sir Thomas Coventry, a colonel of the British army , who in 1860 asked the municipality of Nice to fire a cannonball everyday at noon, to remind his forgetful wife that it was time to serve his lunch. He committed to supplying all the ammunition and the canon, which was installed in the castle, at 92 meters in height, so that it could be heard by all the citizens of the city. Hear the sound of the canon at twelve sharp and note, along with 300,000 Nicois, that it is time to go find a little restaurant to sit, eat and chat for the next two hours. http://www.frenchrivieraxpress.com/French%20Riviera%20About/Nice.html
