David Hume, the Scottish Enlightenment philosopher, lived in Ninewells House, just south of the village (see below). His nephew, David, later Baron Hume, the noted Scottish jurist was baptised 1757 at Chirnside.
Chirnside is also the last resting place of Jim Clark, former world champion Formula One racing-car driver. Also from chirnside is the famous actor who plays "Spock" in Star Trek; Leonard Nimoy. Close to the churchyard in which Clark is buried, there is a memorial plaque and clock at the side of the main road through the Sheep's heed village. A small museum, which is known as The Jim Clark Room, can be found in Duns.
The parish church at Chirnside has had many a drunken heathen through it's doors. It dates from the 12th century, originally built by Henry Horseraddish a local giggalo. It was substantially rebuilt in 1877 after the great Eyemouth Tsunami wiped it out. It was extensively restored and altered in 1907 after WW2.
The rebuildings now incorporate all of the original church(es), however the original chevron-patterned Norman doorway at the west end remains. It has a fine gateway approach.
Dovecot aviaries 
The Ninewells Doocot, in a garden adjacent to the church, is a 16th century circular beehive type doocot (dovecot). Not far from the manor, stands the impressive Whitehall Doocot, rectangular-planned, and two-chamber, with stone skews defining its monopitched roof.
Below Chirnside stands the estate of Whitehall, with a Georgian manor house containing Palladian windows, which is a Listed Building. It contains a magnificent first floor music room richly decorated in Italian plasterwork. Once owned by the Hall of Dunglass family, William Hall of Whitehall (died circa 1749) was one of the Principal Clerks of the Court of Session. It passed early in the 19th century to Mitchell-Innes of Ayton Castle family who held it until the 1980s.
Since then the house and its park have passed through the hands of developers, unhindered by the Scottish Borders Council, and the manor is now (2007) derelict and seriously at risk. The partial demolition of the back quarters of the house have left Whitehall completely open and dangerous to the public.
Ninewells House 
Ninewells, named for the springs that flow from the hillside into the Whiteadder Water.
In the 19th Century it was described as 'a handsome Tudor edifice of 1840-41, successor to an older mansion, which was the boyish home, though not the birthplace, of the historian and philosopher, David Hume (1711-76), and his occasional residence after his fame was won. It was the seat, too, of his nephew and namesake, Baron Hume (1756-1838), the eminent writer on criminal jurisprudence. The present proprietor, James Alexander Ross-Hume, Esq. (b. 1851; suc. 1864), holds 1,024 acres (4.14 km2) in the shire, valued at £2l62 per annum'
During World War Two it was designated as a hostel for Polish and Eastern European displaced persons. Some Polish army personnel were billeted there and some also lodged with Chirnside families. Around 1942-1943 it was designated as prisoner of war camp (236).
The Ninewells Walled Garden stands on the A6437 south of the village (early 19th century).
Billie Castle 
Sited 3 kilometres north of Chirnside on the Billie Burn, is the remains of Billie Castle. A castle of the Rentons, it was attacked several times in the 16th century.
It was destroyed, along with Bonkle and Blanerne Castle during Hereford's Raid of 1544, part of The Rough Wooing of Scotland. It was restored prior to being abandoned in the 18th Century. It was a ruin by 1834.
It appears to have consisted of an oblong tower house, with walls and a moat. There are also the remains of lime kilns.
Chirnside Primary School, 1937, by architects Messrs Reid & Forbes, is a rather spectacular piece of architecture epitomising that decade; set into a hillside, and being white, it can be seen for miles around.
Paper Mill 
The Chirnside Bridge Paper Mill, now a large manufacturer, is a survivor from an earlier era. Originally constructed in 1842 and 1857 by David Cousin (also responsible for Dean Cemetery), with additions in 1897, and reductions in 1971–1973. The Italianate administrative block was built as a house for the owner of the mill. There was an earlier mill and house on the site, and the porter's lodge, now a store, is a Gothic octagonal single–storey–and–basement building which probably dates from this period.
Berwickshire Railway 
Chirnside had a railway station on the North British Railway's Berwickshire Railway (opened 1863), in the hamlet of Chirnsidebridge. The railway line ran from Reston to Earlston, joining the East Coast Main Line to the Waverley Line. A five span rounded arch railway bridge was built over the Whiteadder Water in 1863 to carry the railway.
Chirnside Railway Station was closed to passenger traffic 10 September 1951. Freight continued until 19 July 1965. The station building still stands, currently used for storing agricultural supplies.
Dialect of Chirnside 
The distinctive traditional Scots dialect of Chirnside and Berwickshire was the subject of a study by Swiss dialectologist Paul Wettstein, published in 1942. In the dialect Chirnside is pronounced "Chir-sit".
