Penn Square has been a focal point of Lancaster city for centuries - from the first downtown county courthouse (built in the middle of the square in 1738) through the rise of Watt & Shand and the Griest Building and, ultimately, the Lancaster County Convention Center. 

It's been the home of food vendors, jazz concerts, political rallies and - of course - the annual tree lighting and arrival of Santa Claus.
