Forrest Cemetery Chapel and Comfort Station: The Forrest Cemetery Chapel and Comfort Station (also known as the Ruth Cross Memorial Chapel) are historic structures in Gadsden, Alabama.  The chapel, comfort station, and cemetery gates were built in 1935 by workers from the Works Progress Administration, and designed by local architect Paul W. Hofferbert, who also designed the Legion Park Bowl.  The chapel is designed in Gothic Revival style, with a steeply pitched gable with three lancet arched windows and a square tower with lancet arch opening for the entrance.  The front gate columns and wall are connected to a hipped roof comfort building, which originally housed restrooms, but is now used for storage.  All three are constructed of rough-cut sandstone blocks quarried from nearby Lookout Mountain.  The buildings were listed on the Alabama Register of Landmarks and Heritage in 1988 and the National Register of Historic Places in 1992.

Dinas Cromlech: Dinas Cromlech is a striking rock outcrop in the Llanberis Pass, Snowdonia, in Gwynedd, northwest Wales, with a characteristic "open book" shape.

It was an important venue for a wave of new climbing, for example by Joe Brown: "Cenotaph Corner" (1952, E1, with Doug Belshaw) and "Cemetery Gates" (1951, E1, with Don Whillans).

Elmwood Cemetery Gates: The Elmwood Cemetery Gates mark the east and north entrances to the Elmwood Cemetery in Sycamore, Illinois.  The cast iron gates were likely built in 1865, the year the cemetery opened and the one emblazoned on the gates, though records of their construction have been lost.  While cast iron was commonly used for building facades at the time, the gates are a rare example of its use in landscape architecture.  The gates have a Serlian design with a wide central road entry and narrower pedestrian gates on either side; square columns separate the gates.  An arch bearing the cemetery's name rises above the center entrance, while lintels span the side entrances; both the arch and the lintels feature ornamental designs.  The Illinois Historic Structures Survey described the gates as the best extant example of iron cemetery gate design in the state.
