Kent Union Chapel and Cemetery: Kent Union Chapel and Cemetery is a historic building and cemetery located north of Brooklyn, Iowa, United States.  They are named for the Kent family who moved to Poweshiek County from Putnam County, Indiana in 1853.  They acquired property near Joseph Enochs who had arrived a year earlier.  He and his wife Betsey donated a parcel of land for the cemetery in 1858.  Moses Kent Sr. took possession of the land around the cemetery the following year and the area became identified with the Kent family after that.  By 1870 a school was built next to the cemetery, and both took the Kent name.  The schoolhouse was also a community center where a variety of local functions were held, including church services and Sunday school classes.  Because of a reorganization of the county's public schools, it was relocated a mile to the northeast in 1907.  The following year the Kent Cemetery Aid Society was established by area women.  They were Protestants, Catholics and some claimed no religious affiliation.  They decided to replace the schoolhouse with a union chapel.  They signed a 50 year lease for the land, and held a variety of fundraisers to raise the money to build the chapel.  Many Brooklyn businesses donated materials for the project.  It was dedicated May 23, 1909.  The chapel and cemetery was listed on the National Register of Historic Places in 2009.

Devon County War Memorial: The Devon County War Memorial is a First World War memorial, designed by Sir Edwin Lutyens and situated on the cathedral green in Exeter, the county town of Devon, in the south west of England.  It is one of fifteen War Crosses designed by Lutyens to a similar specification, and one of two to serve as a civic memorial in a city.  The first proposal for the county's war memorial was to complete the construction of a cloister at Exeter Cathedral to be dedicated to the Devon's war dead, but this scheme was abandoned due to lack of funds.  After considering multiple proposals, the Devon County War Memorial Committee commissioned Lutyens to design a War Cross instead.  The committee chose to site the memorial on the green of Exeter Cathedral after scouting several locations.  A war memorial for Exeter itself was being considered concurrently, but the committees for the two projects failed to work together, resulting in two separate memorials—the county memorial by the cathedral and Exeter City War Memorial in Northernhay Gardens.
