Final answer:
Old Kingdom and New Kingdom funerary complexes shared the use of grand scales and temples, but differed as Old Kingdom pharaohs were buried in pyramids while New Kingdom pharaohs favored cut-rock tombs or conventional structures, without building new pyramids.
Step-by-step explanation:
The architectural features that Old Kingdom and New Kingdom funerary complexes had in common included the use of grand scale and the addition of temples or chapels associated with the burial sites. However, a significant difference between the two is that Old Kingdom funerary complexes famously included massive pyramids as the burial structure for pharaohs which encapsulated their bodies and facilitated their journey to the afterlife. In contrast, New Kingdom pharaohs no longer constructed pyramids for their tombs, favoring instead burial in cut-rock tombs or more conventional structures, often decorated with extensive carvings and ornaments. The New Kingdom also saw an evolution in architectural elements with monumental temples, expansive statues, and the introduction of shabti figurines. This era carried forward the tradition of creating grandiose mortuary complexes but altered it in ways that responded to cultural and religious developments.
