A group of college students are learning the how-tos of historical preservation this summer in Towson.The Hampton National Historic Park in Towson is getting a bit of a face-lift. Seven workers with the Hands On Preservation Experience, or HOPE Crew are replacing several porches on the old farm house."There's over 40 different structures here at Hampton, so imagine just trying to maintain 40 different buildings. Many are over 100 years old so it's constant maintenance," National Park Service Ranger Vince Vaise said.The HOPE crews get funding from the National Trust for Historic Preservation to work on preservation projects across the country. Locally, they worked with the civic works program to find interested college students majoring in architecture to hire."As an architecture student, it's always interesting to see how things come together, how structures are built or how things got started to how we got to the point we are now," student Antoine Heath said."I find it interesting when we were demolishing the porches, because I get to see how the structure was built because in architecture when you design, you don't so much think about how it will be built," student Ginikachi Eburuoh said.The students are learning from folks skilled in preservation carpentry to gain the knowledge to eventually carry on the increasingly in-demand job of historical preservation."There's a huge gap between the young people who want to learn about preservation and then getting into the field and what HOPE Crew does is create an opportunity for them to get those skills connect with people who have been doing this awhile, and then also work with the Parks Service to restore some of our nation's most historically significant buildings," said Monica Rhodes, associate director of the Hope Crew.The project at Hampton will be done within a week, but for next summer, the Hope Crew has set its sights on the C&O Canal.
