Two events ended this form of legal education: firstly, a papal bull in 1218 prohibited the clergy from teaching the common law, rather than canon law;[2] and secondly, a decree by Henry III of England on 2 December 1234 that no institutes of legal education could exist in the City of London.

[7] At some point before 1422, the greater part of "Lincoln's Inn", as they had become known, after the Earl, moved to the estate of Ralph Neville, the Bishop of Chichester, near Chancery Lane.

They retained Thavie's and Furnival's Inn, using them as "training houses" for young lawyers, and fully purchased the properties in 1550 and 1547 respectively.

[9] The Inn became formally organised as a place of legal education thanks to a decree in 1464, which required a Reader to give lectures to the law students there.

A third method used was to have individual Fellows promise to fulfill a certain duty; the first known example is from 1435, and starts "Here folowen certaynes covenantes and promyses made to the felloweshippe of Lyncoll' Yne".

[15] In Lord Mansfield's time, there was no formal legal education, and the only requirement for a person to be called to the Bar was for him to have eaten five dinners a term at Lincoln's Inn, and to have read the first sentence of a paper prepared for him by the steward.

[16] A Bencher, Benchsitter or (formally) Master of the Bench[17] is a member of the Council, the governing body of the Honourable Society of Lincoln's Inn.

By the late 15th century, the ruling group were the Governors (who were always Benchers) with assistance and advice from the other "masters of the Bench", and occasional votes from the entire Society.

The present Royal Bencher is Duke of Kent who was elected after the death of the previous incumbent Princess Margaret.

Lincoln’s Inn’s 11-acre (4.5-hectare) estate comprises collegiate buildings, barristers’ chambers, commercial premises and residential apartments.

Lincoln's Inn is surrounded by a brick wall separating it from the neighbourhood; this was first erected in 1562, and it is said that Ben Jonson did some of the brickwork.

From "within" it appears as a cul de sac rather than a square, the two ranges closed to the north with a third which originally contained the library.

George III gave the then-temporary unit the epithet "The Devil's Own", which remains attached to the Regiment to this day.

Although 1 exists near the Gatehouse, the others now only run from 16 to 24, with some buildings having been merged to the point where the entrances for 25 and 26 now frame windows, not doorways.

This remodelling led to the covering of the oak beams with a curved plaster ceiling, "a most barbarous innovation".

[32] The weight of the plaster created the risk that the roof would collapse, and between 1924 and 1927 Sir John Simpson dismantled the entire hall, straightening warped timbers, removing the plaster, replacing any unserviceable sections and then putting the entire hall back together.

[32] The Hall's most famous use as a court is in the start of Charles Dickens' Bleak House, which opens with "London.

Before that, however, it was open to any member or servant of the society; in 1829 a former Preacher was interred, and in 1780 William Turner, described as "Hatch-keeper and Washpot to this Honble.

Traditionally, the bell would chime a curfew at 9 pm, with a stroke for each year of the current Treasurer's age.

[40] A substantial William Hill organ replaced it in 1856; a model designed at the peak of his skill, with thick lead and tin pipes,[41] a set of pedals, and three manuals.

The new building was designed by Philip Hardwick, with the foundation stone laid on 20 April 1843 by James Lewis Knight-Bruce, the Treasurer.

[34] The lower ground floor was divided by a mezzanine in 2007 and the upper part became the Members Common Room for informal dining and with a lounge.

In effect it is a club providing bar and restaurant facilities for all "entitled" persons, meaning members of the Inn and its bona fide tenants.

[44] The current Library was built as part of the complex containing the Great Hall, to the designs of Hardwick and was finished in 1845 being formally opened by Queen Victoria.

The only other lending service available is offered by Middle Temple Library, which permits barristers and students of any Inn, on production of suitable ID, to borrow current editions of textbooks that are not loose-leaf – but not any other material – half an hour before closing for return by half an hour after opening the following day.

[50] The Gatehouse is a large tower four stories high and features diagonal rows of darker bricks, along with a set of oak gates that date from 1564.

The solution of providing a 150-seat Lecture Theatre and Tutorial Rooms was to exploit the space under the large east terrace of the Great Hall.

On 13 December 2018, HM Queen Elizabeth II along with the Duke of York (Royal Bencher of the Inn) officially opened the Ashworth Centre and re-opened the Great Hall following its renovation.

Around 1699, Sir Richard Holford discovered the Inn's own coat of arms on a manuscript, granted to them in 1516.

The arms are "azure seme de fer moline or, on a dexter canton or a lion rampant purpure".
