Beginning Wednesday, July 1, the Museum will conduct cannon demonstrations daily between 2:15 and 2:30 pm. Daily demonstrations will continue through Labor Day weekend, and are part of our ongoing efforts to create interesting and engaging activities for Museum visitors. It is our sincere hope that the expanded schedule will not cause undue stress among our neighbors on Oregon Hill.

I also would like to give you an update on the work that is being done to the canal wall at the Tredegar site. All the willow oaks on the south side of the wall, and the small scrub trees growing close to the north side of the wall, have been removed. Craddock Masonry, Inc. is conducting repair and reconstruction, which is under way. Where the extent of damage requires it, the top three courses will be rebuilt and the entire length of the wall sealed. Holes and erosion of the wall will be repaired. Old bricks that are in good condition will be reused, with matching vintage brick being used as needed. This work is scheduled to be finished by late July.
