this sunday on q&a, eric larson on his book "dead wake," the last sinking of the lusitania. erik larson: the question is what happened to the lusitania? why was it allowed to enter without escort, without the kind of detailed warrants that could have been provided to the captain, but was not. this is led to very interesting speculation that that was the ship essentially set up for attack by church hill or someone in the admiralty. it's interesting. i found no smoking memo, and believe me i would have found a smoking memo. there was nothing from churchill or shush her or anyone saying, let's let the lusitania go into

the irish sea. nothing like that exist. >>, sunday night at 8:00 eastern and pacific on c-span's q&a. each week american artifacts takes you to places and looks at artifacts in american history. bacon's castle was occupied nathaniel bacon supporters during the political uprising. originally called arthur allen's brickhouse, we learn about the structure and some virginians who called it home. in the director of the museum. today we are a weekend castle. -- bacon's castle. bacon's castle is on the national register of historic

sites. we are the oldest dwelling in north america. it is a very rare architectural style. it's youthe other two are invertedn barbados. this room would have been directly above where visitors would have entered into bacon's castle until the addition was built and the entrance was moved. you can really get a fantastic view of why we specifically refer to this house as being in the style of architecture and that would be if you look out

the window you can see the flemish gables and the triple stacked to on either side -- chimney on either side of the house. on the opposite side we have hme on the second -- a chimney on the second floor and a kitchen fireplace. this is where we have the chance to get up close and personal with the architectural style. this is the anniversary of its being built, it was built in 1665 stop we are very excited we are able to continue preservation efforts and hopefully we will keep it around for another 350 years.
