SCP-1042: "Ghost Stone"

 SCP-1042 is a standard brick used in foundation construction, typical of homes built in the Victorian era. Analysis has shown that SCP-1042 has similar composition to those made in ███████ during ██████, though closer inspection shows an unusual latticework structure on a molecular level. When introduced to low level electromagnetic fields or struck with a ferrous object, 3-dimensional visual and auditory "projections" of past events appear. These projections are frequently accompanied by the entity designated SCP-1042-1.
