Support the Park

In order to protect the Riordan story, we must first preserve the house. A wood structure needs constant upkeep and funding to keep that happening. We are pleased to report that we have secured funding and the house will be painted in spring 2022.

We are currently working on restoration work on windowsills, siding and vigas. Vigas on the side of the Riordan Mansion

Your donation can help us conserve and protect these amazing resources. Considering supporting restoration efforts at Riordan Mansion State Historic Park with a donation through the new Adopt-a-Viga program.

What is a Viga?

Vigas are the wood log ends that extend out from the roof and sides of the Riordan Mansion. Usually vigas are part of the structure of a building, but here they are purely decorative and are short logs attached to the building. There are 392 vigas between the two Riordan family homes. Each costs a little over $1,000 to replace and helps maintain the home in the condition in which it was built, helping us tell the story of the Riordans!

How the Program Works

  • A viga will be assigned to you and its likeness attached to the Riordan Mansion model in the Visitor Center.
  • You will receive a wooden thank you ornament with your viga number and adoption date burned on the back.
  • Once your viga has been replaced, a photo of the new viga will be sent to you via email. Please be patient, there are many factors that will affect when your viga will be replaced.

Other amounts - We welcome donations large and small. Please contact the park if you would like to fund another project or just supply funding for ongoing repairs and maintenance.
