Jackson Square is located in the French Quarter of the city and is dominated by the three tall spires of St Louis Cathedral.
This is a stunning part of the city, and the cathedral is beautiful, as you can see by the pictures. To one side of the cathedral is The Cabildo, former headquarters of the Spanish colonial government. These buildings are so photogenic, you will just want to gaze at them.
Opposite the cathedral is the square itself, which is a lovely park-like area. There is a bronze statue of Andrew Jackson, who saved New Orleans during the war of 1812.
There is little more to say about this area, other than it is beautiful and worth a visit.
