The name comes from the Gaelic "cill" ("cell"), and the name of Saint Marnoch or Mernoc who is also remembered in the name of Portmarnock in Ireland, and Inchmarnock. It may come from the three Gaelic elements "mo", 'my', "Ernán" (name of the saint) and the diminutive "ag", giving "Church of My Little Ernán". Some people think that the saint founded a church there in the 7th century. There are 12 Church of Scotland congregations in the town, plus other denominations. In 2005, the Reverend David W. Lacy, minister of the town's Henderson Church, was elected Moderator of the General Assembly of the Church of Scotland.
The core of the early town appears to have lain around what is now the Laigh Kirk (Low Church), although the oldest parts of the current building are no earlier than the 17th century, extending north and northwest. A comparatively modest settlement until the industrial revolution, Kilmarnock extended considerably from around 1800 onwards. This resulted in formal, planned developments such as King Street, Portland Street, Saint Marnock Street, and latterly John Finnie Street; the latter often suggested as one of the finest Victorian planned streets in Scotland.
Areas of Kilmarnock include:
Kilmarnock's traditional industries were based around textiles and heavy engineering: e.g. locomotives (Andrew Barclay and Sons) from 1837 through 1970, and valves (Glenfield and Kennedy), which are still in production; and carpets (manufactured by BMK) from the early 1900s.
The carpets manufactured in Kilmarnock were internationally known for their quality and intricacy since the late 1800s. Many locations around the world chose to install BMK carpets. Famously, RMS Titanic was carpeted using carpets manufactured by Stoddard Carpets, the parent company and successor to BMK. Primarily due to a move by the UK market towards laminated and hard-wood flooring, but also partially due to a long decline in the industry in the area as well as cheaper, but noticeably less hard-wearing foreign competition, carpet-making finally ceased in Kilmarnock in early 2005.
Archibald Finnie and his family lived at Springhill House (now a nursing home) near the Grange Academy. They owned many coal mines, pits and other companies in Springside and other places. John Finnie Street is named after one of the family. Shoes were also a major product for some time, with Saxone having a factory in the town on the site of where the Galleon leisure centre is now.
Kilmarnock had one of the earliest tram railways in the world, running to Troon over the (recently restored) Laigh Milton viaduct. The Glasgow and South Western Railway also set up their works here, producing nearly 400 locomotives by the time it was absorbed by the London, Midland and Scottish Railway in 1923. Some work continued, but heavy repairs were sent to St. Rollox. Locomotive repairs finished in 1952, and the works closed in 1959. Nevertheless locomotives are still made by Hunslett-Barclay, as well as the maintenance of existing diesel and electric multiple units.
From 1946 tractors were also built in Kilmarnock, with a large Massey-Harris factory present on the outskirts of the town. It later became Massey-Ferguson, before closing in 1980. Glenfield and Kennedy still survives albeit with a fraction of its former workforce, which at its height numbered in the thousands. Kilmarnock however is still home to the world famous Johnnie Walker's brand Scotch whisky. On the outskirts of the town is Scotland's first privately run prison, HM Prison Kilmarnock.
The textile and manufacturing sectors across Scotland suffered significant decline in the postwar period, and in particular from the 1960s, in the face of greater foreign competition. Kilmarnock was no exception, with the closure or significant reduction of many of its traditional large employers: Glenfield and Kennedy, Massey Ferguson, BMK, and Saxone. Although significant attempts have been made to halt this decline and attract new employers, Kilmarnock saw a continuing net loss of jobs in the five years to 2005.
Although traditionally a main shopping area for most of the surrounding districts, patterns have changed over the last 20 years; traditional centres such as Ayr have been joined by new developments at Braehead and East Kilbride.
This difficult economic climate is most visible in the town centre, the eastern part of which has been extensively redeveloped, with important historic buildings such as King Street Church and the Town Hall being demolished, and Duke Street (the link from Kilmarnock Cross to the Palace Theatre and out to the London Road) built over.
More recently Portland Street, which formed the northerly part of the main shopping area, lay abandoned for many years due to a decline in retail trade and in the face of possible comprehensive redevelopment. The street has now been redeveloped, but has not yet regained its former degree of popularity, with a Gala Bingo and a J.D. Wetherspoons taking up much of one side of the street and the rest largely occupied by chain stores.
In 2004, the "Rough Guide to Scotland" described the town as "shabby and depressed, saddled with some terrible shopping centres and a grim one-way system". The town, however, contains several parks such as Howard Park, Dean Park, and Kay Park, and residential areas including London Road, Dundonald Road, McLelland Drive, and Howard Park Drive. The town also boasts a collection of gift shops, cafes, bars, and restaurants within the very desirable Bank Street area, whilst offering retail options within its retail parks at Queen's Drive and Glencairn Square.
According to the local press in November 2007, the new SNP council have drawn up a "Top Ten Hit List" on 'eyesore' buildings in the town, and their owners and have revealed plans to crack down hard on property owners who have left their buildings fall into disrepair. A plan of action is being carried out to get something done with each of these sites. Many of the buildings in disrepair are irreplaceable listed buildings such as the former ABC cinema (previously the King's Theatre) on Titchfield Street.
A four-star hotel recently opened next to Rugby Park, the home of Kilmarnock F.C., and new restaurants, such as "Merchants" and the award winning "Jefferson Restaurant" have opened in the town centre.
Regeneration activities have been discussed for Kilmarnock town centre; in early 2006, an application to Historic Scotland's Conservation Area Regeneration Scheme was successful, and as of July 2006 an application under the Heritage Lottery Fund's Townscape Heritage Initiative Scheme was pending. Work has pretty much finished on a quality housing development on the gapsite of the former Kilmarnock Infirmary north of the town centre.
In the past there have been major efforts to improve the quality of life for residents in the town's worst housing estates, especially in parts of Shortlees, Longpark and Onthank. Though the physical rehabilitation of housing in these areas has partly tackled the underlying problems of social exclusion, Onthank is arguably that most successful area of regeneration in question.
Much new quality housing has been constructed on the northern fringes of the town, in order to service the demand for commuter housing. With a journey time of 20 minutes from Kilmarnock to Glasgow (roughly half that of the existing train service), the M77 motorway has transformed the link between Glasgow and Kilmarnock. The upgrading of the A77 route to Glasgow to the M77 motorway in 2005 has made Kilmarnock more accessible for commuters, and recent house price increases have reflected this.
In 1812, the famous Kilmarnock and Troon Railway opened, mainly to carry coal from the area to the harbour at Troon, but also carrying passengers.
