A cellar cock-pit with glass lights was advertised in the sale or lease of the Seven Stars in Monkseaton in 1814. Cock-fighting was a popular pastime throughout the eighteenth and nineteenth centuries. It was often referred to as the "Royal Sport". The pursuit had a number of notable folloers including the Duke of Cleveland and Earl of Northumberland. Contests were advertised as "Gentlemen's Subscription Mains" but the "sport" was actually popular with all classes. Established rural cock-pits were often no more than an uncovered earthwork, they were generally located in or near to villages. This feature is about 400m away from Grindon village. The pis consisted of a central fighting platform, 2.5m or more in diameter, surrounded by a shallow ditch and external bank. During the contest low boards were put on the platform to contain the birds. Three classes of birds were normally used - stags which were under one year old, cocks which were older, and blinkards or one-eyed veterans. Birds who refused to fight were known as "fugies" or "hamies". Cock-fighting became a well publicised and financially well-backed "sport". As well as the local venues, cock-fighting also took place at local race meetings, usually in the morning, followed by the horse racing in the afternoon. Events were advertised in the local press, such as the Newcastle Courant. Prizes were normally in the region of 10-20 Guineas, however there were occasions when they could be as much as 500 Guineas. Sometimes the prizes for cock-fighting were of greater value than the awards for the local horse races. By the early nineteenth century opposition against the barbarity of cock-fighting was increasing, due to improved education and a religious revival which exerted moral pressures on society. Many of the local gentry turned to other pastimes, such as fox hunting, which at the time was more politically and socially acceptable.
