New Castle, founded by Peter Stuyvesant in 1651 as the seat of the New Netherlands government, served as the colonial capital of Delaware until 1766.  The Historic District offers a broad range of architectural styles essentially unchanged from the 17th, 18th and 19th centuries.

Since its founding in 1934, the New Castle Historical Society has worked to promote historical awareness, and encourage the preservation of historical architecture, documents and material culture in New Castle.  Three historic houses and gardens managed by the Society – the Amstel House, Dutch House and Old Library Museum are open to the public for group and individual tours. The Historical Society is also involved in educating the public about the history of New Castle and in disseminating information through exhibits, programs, lectures, publications and resource materials. The Historical Society has a broad base of community membership for which it provides programming and from which it derives volunteer support.  (

The Preservation Trades Network (PTN) is a non-profit membership organization committed to representing and strengthening the role of the traditional trades in the preservation process through education, networking, and outreach.  PTN is an umbrella organization that unites a variety of trades involved in building and preservation including: timber framing, carpentry, masonry, plaster, painting and decorative arts, historic roofing, and metallurgy.  This networking process, which is fundamental to the PTN effort, has established a strong foundation for collaboration and exchange with programs in the United States and abroad.  Since 1997, PTN has presented an annual International Preservation Trades Workshop (IPTW), attracting presenters and participants from nine different countries as well as the US and Canada.  The New Castle Preservation Trades Workshop will bring the successful IPTW format to a regional and local setting.  PTN is working to sustain the success of existing trades education programs, recognizing the contributions of the masters of the trades, and creating opportunities for future generations of tradespeople.  ( and
