The profile is a cross-section of soil layers. The layers can be dated by historical events. The uppermost layer was the yard paving laid between 1770 and 1800. In the tenth layer was found an abundance of wood shavings, which point to construction work carried out at the site in the 1770s. A wood shaving layer appearing five layers lower possibly points to events in 1713. The fire that devastated the city in 1654 helps to date the 22nd layer.

Studies of pollen and plant remains were conducted on land-fill materials recovered from the eastern and western edges of the profile. A palaeoecological study is the study of an ancient environment. The work is based on the fact after plants die minute fragments of them remain in the soil. By going through the soil layers in a systematic way, one can unravel the plant species present in different layers of the excavation area.

Research results provide information about the food economy and living environment of the 17th and 18th centuries. The main cereals used as food in the area were barley, rye and oats. Flax was cultivated as a raw material for cloth. Figs were purchased for medicines or for cooking; dried figs were used as a stimulant. Local berries were gathered from the nearby woods and fields or bought from merchants. Raspberries and strawberries were the most common. Bearberries and nuts might also have been consumed. Poppies were probably bought as a drug, as was henbane, but people could also grow them close to their dwellings.
