Joseph Priestley (1733-1804) was known for identifying carbon monoxide, but mainly as the…read morediscoverer of oxygen in 1774. He was also a theologian, educator, political activist and writer. He spent the last years of his life in then rural Northumberland, Pennsylvania. He was a strong supported of the political ideas of the french revolution and had supported many religious Dissenters (both no-no's in his homeland of England), for this his house, library & laboratory were burned down, he was accused of treason and then he immigrated to The United States. First settling in Philadelphia, then moving to northumberland, he had hoped that moving to such a rural and secluded area would perhaps give him some breathing-space and time to think. He wasn't welcome as a preacher in Northumberland, but founded the first congregation of Unitarian faith in Philadelphia. His house was equipped with a laboratory, where he conducted experiments. His ideas greatly influenced Thomas Jefferson and the Constitution, and also his education planning is the basis for the liberal arts college. This is basically a tour of his original house, it has been modified since then. takes about a half-hour. 4.00 admission per person.

Dan pretty much hits the nail on the head in his review. I'd heard of the Joseph Priestley House…read morebefore, but I'd never visited it. Not only did Priestley discover oxygen, he also conducted early experiments in electricity and counted Benjamin Franklin, Thomas Jefferson, and James Watt among his friends. His teachings were so controversial that his house in Birmingham England was burned to the ground. He and his family fled Engand and Priestley spent the last decade of his life in Northumberland. The Joseph Priestley House is a National Historic Landmark and from the outside, it looks like a typically unassuming English gentleman's estate. But it's really easy to spend some time in here. Priestley and his family not only lived here, he had his laboratory here too. And I'm happy to say that the lab has been recently renovated. When the lab was renovated, it was done so without intruding on the elements of the house. The exhibit is set as though Priestley is at work investigating carbon monoxide in his Northumberland laboratory. Reproduction glassware pieces were selected, based on pieces that Joseph Priestley was known to have used here. The original laboratory glassware is now at the Smithsonian Museum in Washington, DC. Other renovations include two representative furnaces with chimneys and a fume hood spanning the width of the lab. There's also a lot of family history in the house. His spouse Mary Priestley did a lot of the planning for the new house. She passed away, however, two years after they arrived in Northumberland and she never saw the completion of the house. As a widower, Joseph Priestley lived here with his eldest son, Joesph Priestley Jr and his daughter-in-law and his grandchildren. In 1919 Dr. George Gilbert Pond bought the house at auction. Dr. Pond was dean of the School of Natural Sciences at Pennsylvania State College (now Penn State). After his death in 1926, the college purchased the house and built the Pond House in his honor. It was used as a firepoof museum for Joseph Priestley's artificats. It once served as a visitor center, however plans are afoot to adapt it for public meetings and exhibits. I think that visiting small historical houses such as Priestley's can be just as rewarding as visiting well-known museums. If you visit the Priestley House, do the "Priestley Pilgrimage" by also visitng the Joseph Priestley Memorial Chapel, Riverview Cemetery and Northumberland's Historic District.

I visited the Cornwall Iron Furnace for the first time during their 345th Charter Day celebration,…read moreand I'm so glad I finally made the trip. This historic site had been on my list for a while, and with the beautiful weather and special event happening that day, it felt like the perfect time to go. Interestingly, I had only learned about the iron furnace a few months ago. I've always been fascinated by history especially the processes behind how things were made so visiting a place like this was incredibly intriguing. Seeing such an important piece of industrial history still standing today really makes you appreciate the ingenuity and craftsmanship of the people who built and operated it centuries ago. My group tour started at 12:45 PM and lasted a little over an hour. One thing I really appreciated was that we got to hear from several different volunteer guides throughout the tour rather than just one person leading the entire time. Each guide shared their own knowledge and perspective about different parts of the furnace and its operation. They were all incredibly informative and made the history easy to understand, even if you're not familiar with iron production. By the end of the tour, I honestly felt like I had learned dozens of fascinating facts about early iron-making, the daily lives of the workers, and how complex the entire process was. Workers often had 12-hour shifts to keep the furnace operating, which really highlights the amount of labor and coordination required. Standing inside the furnace structure itself was a unique experience. Even though it was warm outside, it actually felt noticeably cooler inside the building, which was surprising. You could really see the age of the structure and imagine the incredible amount of work that went into building and maintaining it. A few helpful things to know before you visit: Parking: Because of the Charter Day event, we were able to park directly on the property near the furnace building. However, there is also additional parking across the street and slightly down a hill, which requires crossing the road to reach the site. Restrooms are located inside the Welcome Center, where the gift shop is located. These appeared to be the only bathrooms on the property. Visitor tips: *Wear comfortable shoes, as there are stairs involved during the tour. *No food or drinks are allowed during the tour. *Plan to spend about an hour or a little more if you take the guided tour. Overall, this was a really enjoyable and educational experience. It gave me a much deeper appreciation for the hard work, skill, and innovation that went into early American industry. If you enjoy history, learning how things are made, or exploring unique historic sites in Pennsylvania, visiting the Cornwall Iron Furnace is absolutely worth adding to your list. Highly recommend taking the guided tour you'll walk away learning far more than you expect.

I absolutely love history and history museums and loved everything about it. My girlfriend, 11-year-old son and I visited on a Saturday afternoon on a trip to Harrisburg and Hershey. We took the tour and definitely got our money's worth ($18 for the three of us which included a AAA discount)! Started with a 15 minute video, then a guided tour by Beth which lasted over an hour, during which we got to see the furnace from all angles. Beth was very knowledgeable and also very patient with my son's many questions. The property also boasts a small museum and gift shop in the building that formerly housed the operation's charcoal. The gift shop is excellent. Among other things they have a range of cast iron products, as well as many cookbooks with suggested uses. This was an excellently run museum that I can definitely recommend to others who enjoy American history.

It's in the shape of a 16-foot circle on the south-west corner of Penn Square, and its greenish tint is simply the result of a natural patina from the fountain's welded copper panels. As you make your way to the Central Market, you really can't miss it. Built in 1972, the fountain was designed to soften the constant traffic noise at the heart of Lancaster, just steps from Central Market. Water rises from the base and spills over the textured copper surfaces, creating a steady sound that helps muffle the busy intersection around it.
