Since the Renaissance period, staircase towers were markedly more decorative and representative of status. Stairs were now rarely hidden or built externally, but there were both artistically designed, curved and straight-running staircases inside the building with ornate ceilings and railings (e. g. Château de Chambord, Palazzo Barberini and Château d'Azay-le-Rideau or Château de Chenonceau). With the increasing construction of straight staircases with intermediate landings (the modern stairwells) separate staircase towers became gradually rarer.
