A vestry refers to a robing and storage room in or attached to a place of worship. It also referred in England to the committee for secular and church government for a parish which met in the vestry of the parish church, and consequently became known colloquially as the "Vestry".
A vestry is a room in a church or synagogue in which the vestments are kept, and in which the clergy and choir don these liturgical clothes for worship services. Valuable or sacred items such as communion vessels or collection plates may be kept there, usually in a secure safe, along with official records such as registers of marriages and burials.
In Welsh chapels, the room is often the location of a tea served to the congregation, particularly family members, after a funeral, when the congregation returns to the chapel after the burial or cremation.
The Vestry Committee in England
The vestry was a meeting of the parish ratepayers chaired by the incumbent of the parish, originally held in the parish church or its vestry, from which it got its name. The vestry Committees were not established by any law, but they evolved independently in each parish according to local needs from their roots in medieval parochial governance. By the late 17th century they had become, along with the County magistrates, the rulers of rural England. 
In England, until the 19th century, the parish Vestry Committee was in effect what would today usually be called a parochial church council, but was also responsible for all the secular parish business, which is now the responsibility of a parish council.
The original unit of settlement among the Anglo-Saxons in England was the tun or town. The inhabitants met to carry out this business in the town moot or meeting. At this they appointed the various officials and the common law would be promulgated. Later with the rise of the shire, the township would send its reeve and four best men to represent it in the courts of the hundred and shire.
However, the independence created by the Saxon system was lost to the township by the introduction of the feudal manorial Court Leet which replaced the town meeting. The resistance of inhabitants to these changes led to a new form of township or parish meeting, which dealt with civil and ecclesiastical affairs. This new meeting was supervised by the parish priest, probably the best educated of the inhabitants, and it evolved to become the vestry meeting.
With the decay of the feudal system, the vestry meetings succeeded in acquiring greater responsibilities, they having the power to grant or deny payments from parish funds. They were later given the task of administering the Edwardian and Elizabethan systems for support of the poor. With their resumption of civil responsibilities, the ecclesiastical parishes acquired a dual nature and might therefore be classed as civil as well as ecclesiastical parishes. In England, until the 19th century, the parish vestry was in effect what would today usually be called a parochial church council, but was also responsible for all the secular parish business. Records of parish business would be stored in a "parish chest" kept in the church and provided for security with three locks, the keys to which would be held by the incumbent and the churchwardens.
The vestry had a number of legal obligations. The vestry was responsible for appointing parish officers, including churchwardens, overseers of the poor, sextons and scavengers. Depending on local arrangements the vestry could also be responsible for constables and nightwatchmen.
In 1835 more than 15,600 ecclesiastical parish vestries looked after their own: churches and burial grounds, parish cottages and workhouses, their common lands and endowed charities, their market crosses, pumps, pounds, whipping posts, stocks, cages, watch houses, weights and scales, clocks and fire engines. Or to put it another way: the maintenance of the church and its services, the keeping of the peace, the repression of vagrancy, the relief of destitution, the mending of roads, the suppression of nuisances, the destruction of vermin, the furnishing of soldiers and sailors, even to some extent the enforcement of religious and moral discipline. These were among the multitudinous duties imposed on the parish and its officers, that is to say the vestry and its organisation, by the law of the land.
At their most active, just prior to removal of Poor Law responsibilities, the vestries spent not far short of one-fifth of the budget of the national government itself. However, this was the high point of the parish vestry. During the 19th century the parish vestry progressively lost its powers to ad-hoc boards and other organisations, such as the loss of responsibility for poor relief through the Poor Law Amendment Act 1834. From 1837 the provision of support for the poor was no longer the direct responsibility of the vestry, but came under elected boards of guardians for single parishes or poor law unions. In the London area, vestries were incorporated under the Metropolis Management Act 1855 to create civil bodies for parishes, which were distinct from the ecclesiastical vestries. In another example, Sanitary Districts were established in England in 1875 and took these responsibilities from the parish. Such replacement boards were each able to levy their own rate in the parish. Consequently the church rate ceased to be levied in many parishes and was abolished altogether in 1868.
However, proliferation of local bodies led to fragmentation of local government resonsibilities and became a driver for the 1894 Local Government Act. This was expressed by H H Fowler, President of the Local Government Board, who said in the parliamentary debate for the 1894 Act....
"62 counties, 302 Municipal Boroughs, 31 Improvement Act Districts, 688 Local Government Districts, 574 Rural Sanitary Districts, 58 Port Sanitary Districts, 2,302 School Board Districts ... 1,052 Burial Board Districts, 648 Poor Law Unions, 13,775 Ecclesiastical Parishes, and nearly 15,000 Civil Parishes. The total number of Authorities which tax the English ratepayers is between 28,000 and 29,000. Not only are we exposed to this multiplicity of authority and this confusion of rating power, but the qualification, tenure, and mode of election of members of these Authorities differ in different cases."
The secular and ecclesiastical duties were finally separated nationally when a system of elected rural parish councils and urban district councils was established under the 1894 Local Government Act. This replaced the parish vestry with a parish council or parish meeting to manage all secular parish matters.
Open and select vestries
A "select vestry" was an administrative committee of selected parishioners. This committee was also known as the "close vestry". The "open vestry", which selected many of those committee members, was a meeting open to the general public who were rate-paying residents. There were both open vestries or select vestries, although in practice the division was somewhat blurred. Open vestries were rather like today's parish meetings, but some select vestries acted more like the pre-Municipal Corporations Act 1835 borough councils, with co-option of members rather than by open election.
An open vestry was a general meeting of all inhabitant rate-paying householders in a parish.
A select vestry or "close" vestry was the governing body of a parish, the members generally having a property qualification and being recruited more or less by co-option. The open vestry elected the bulk of the select vestry members or, if dissatisfied, could exercise their power to do so.
Ecclesiastical use today
Following the removal of civil powers in 1894, the vestry meetings continued to administer church matters in Church of England parishes until under the Parochial Church Councils (Powers) Measure 1921 Act Parochial Church Councils were established as their successor on church matters. Since then, the only remnant of the Vestry Meeting has been the Meeting of Parishioners, which is convened annually solely for the election of churchwardens of the ecclesiastical parish. This is sometime referred to as the "Annual Vestry Meeting". All other roles of the Vestry Meetings are now undertaken by parochial church councils.
The term vestry continues to be used in some other denominations for a body of lay members elected by the congregation to run the business of a church parish, such as in the Scottish Episcopal Church.
