The Pennsylvania Historical and Museum Commission is partnering with Thaddeus Stevens College of Technology, the Preservation Trades Network, Inc. and other organizations to bring one of the largest gatherings of preservation and traditional trades people and enthusiasts in the world to Lancaster, Pennsylvania. The 15th annual International Preservation Trades Workshop (IPTW) will be held August 2-6, 2011 on the campus of Thaddeus Stevens College of Technology, 750 E. King Street in Lancaster, Pennsylvania. IPTW 2011 will bring together hundreds of the best preservation and traditional trades crafts people, as well as preservation architects, preservation consultants, building trades contractors and others from the US, Canada, Europe and beyond, who are interested in learning more about preservation and traditional trades techniques, tools, materials and practices. For those who work in the preservation and traditional building trades, this is a gathering of the “tribe”. For others, it offers a unique opportunity to see some of the finest crafts people at work and learn more about how historic building preservation is accomplished in construction.
