Federal Architecture vs Neoclassical Architecture

Federal Architecture was influenced by Neoclassical Architecture — shaped by Adam-style Neoclassicism and a republican taste for Roman models.

Massachusetts State House, Boston — Federal

Federal Architecture

The classical style of the early American republic — refining colonial Georgian with lighter Adam-derived ornament, delicate detail, and emblems of the new nation.

  • Elliptical or semicircular fanlights over the entrance
  • Slender proportions and flat, restrained brick façades

Panthéon, Paris — Neoclassical

Neoclassical Architecture

A disciplined return to the pure forms of Greek and Roman antiquity — calm symmetry, columns and porticoes, and noble restraint after Baroque excess.

  • Symmetry, clear geometric volumes, and calm proportion
  • Domes and triangular pediments
  • Correct use of the Greek and Roman orders
  • Restrained, sparing ornament compared to the Baroque
