In a Baroque palace, access down an enfilade suite of state rooms typically was restricted by the rank or degree of intimacy of the visitor. The first rooms were more public, and usually at the end was the bedroom, sometimes with an intimate cabinet or boudoir beyond. Baroque protocol dictated that visitors of lower rank than their host would be escorted by servants down the enfilade to the farthest room their status allowed. If the visitor was of equal or higher rank, the host would advance down the enfilade to meet their guest, before taking the visitor back.

At parting, the same ritual would be observed, although the host might pay their guest a compliment by taking them back farther than their rank strictly dictated. If a person of much higher rank visited, these rituals extended beyond the enfilade to the entrance hall, the gates of the palace, or beyond (in modern state visits, to the airport).

Memoirs and letters of the period often note the exact details of where meetings and partings occurred, even to whether they were in the centre of the room, or at the door.^{[citation needed]}

Royal palaces often had separate enfiladed state apartments for the king and queen, as at the Palace of Versailles, with the grand appartement du roi and the grand appartement de la reine (not to mention the petit appartement du roi), or at Hampton Court Palace. Such suites also were used for entertaining.

Noblemen's houses, especially if a visit from the monarch was hoped for, often feature enfiladed suites, as at Chatsworth House, Blenheim Palace, the Château de Louveciennes, or Boughton House. The bedrooms in such suites were often only slept in on royal visits, although as with many grand bedrooms before the nineteenth century, they might be used for other purposes. Other enfilades culminated in a room used as a throne room. The Palace of Westminster, shown below, comes into this category, as the monarch sits on a throne in the chamber of the House of Lords during the State Opening of Parliament.

Sir Charles Barry's Palace of Westminster, more commonly known as the Houses of Parliament, has an enfilade of three Royal apartments that continues through the two legislative Chambers of the Lords and Commons. The enfilade of State Rooms presents a view from the Robing Room and Royal Gallery – B and C on the plan at right – through to the Prince's Chamber. From the throne in the adjacent Lords' Chamber (D) there is an uninterrupted view through three lobbies – Lords', Central, and Members' Lobby – to the Speaker's Chair in the Commons Chamber at the other end of the Palace. (Lords' Lobby and Members' Lobby are the round and square spaces to the left and right of E on the Plan)

Barry also used a number of enfilades in his extension to the National Gallery, London,^[1] built as an art gallery. These have been extended and added to in the recent Sainsbury Wing (despite the wing being at an angle to the earlier building), so that now the view down the longest enfilade traverses fifteen rooms.^[2]
