There are so many amazing things to see and do in Pittsburgh. Unfortunately, sometimes our wallets contain more dust than dollars. These 9 places in The Steel City have free admission so you can still explore without breaking the bank. Here are free places to go in Pittsburgh that are low on cost but rich with fun.

1. The Fort Pitt Block House

Stand where history was made. The Fort Pitt Block House, built in 1764, played an important role in the French & Indian War. The only remnants left of Fort Pitt, the block house served as a British fortification, designed to protect the British army from the Native Americans. Admission is free and visitors will get insight into the history of Fort Pitt by viewing digital demonstrations and exhibits and by talking with educators. The Fort Pitt Block House is open every Wednesday through Sunday from 10:30 a.m. to 4:30 p.m. from April through the end of October. Winter hours, from November to the end of March, are Friday through Sunday from 10:30 a.m. to 4:30 p.m.

2. Allegheny Observatory

Drink in the beauty of the night sky at the Allegheny Observatory at the University of Pittsburgh. Run by the Department of Physics and Astronomy, the Allegheny Observatory offers free public tours every Thursday evening from 8 p.m. to 10 p.m. from April through August and Friday night tours in September and October. Each tour, which requires advanced reservations, consists of an introductory video, a guided tour of the Allegheny Observatory, and the chance to view the night sky from the facility's telescopes.

3. The Nationality Rooms at the Cathedral of Learning

Travel around the world without leaving the Burgh when you visit the Nationality Rooms at the Cathedral of Learning in Oakland. Each room will introduce you to a different country – from Africa to Yugoslavia – and to a different culture. Free self-guided tours are limited during the school year but are open daily during summer break, which typically runs from the end of April until the beginning of September. You can also take an online tour of the Nationality Rooms.

4. Old Allegheny County Jail

Local lure tells stories of a jail so haunted that former prisoners begged the warden – and were obliged – to move to another part of the jail due to constant wailing from a ghostly figure. The Old Allegheny County Jail Museum is now all that remains of the jail; the rest of it has been renovated into the Family Division of the Allegheny County Courts. Head to the museum every Monday, through October 31 this year, at 11:30 to receive a free tour with information provided by a local docent.

5. Pittsburgh Glass Center

Discover the art of glass blowing at the Pittsburgh Glass Center which, in addition to holding classes for a fee, features an exhibition area of artists' work. View the glass art, watch artists work, and, if you're lucky, catch a glass blowing demonstration, as you stroll through the free self-guided tour. The Pittsburgh Glass Center is open daily, although the artists' studios are closed on Mondays.

6. Big Mac Museum Restaurant

Head just outside of Pittsburgh to North Huntington and you'll find the Big Mac Museum Restaurant. That's right – the Big Mac has its own museum, in part because the famous burger was invented by a Pittsburgh franchisee, Jim Delligatti. Tour the museum for free (be prepared to plunk down some cash for a meal or a snack) where you'll discover the World's Largest Big Mac (okay, a replica of one), view the high tech displays, and send the kids to play in McDonald's best play place. The museum is open daily.

7. Pittsburgh Parks: Cinema in the Park

Several area Pittsburgh parks become outdoor movie theaters every summer with Cinema in the Park. Pittsburghers are invited to bring their blankets, their lawn chairs, and plenty of snacks to one of several area parks to watch such feature films as Maleficent, The Wizard of Oz, and Selma. Area parks that host the free Cinema in the Park, which runs from June through August, include Arsenal Park, Brookline Memorial Park, Schenley Park, Highland Park, Grandview Park, Riverview Park, and Overlook Park.
