Room S had the first old yard paving encountered when entering from the west. It was laid in the area of plots 1 and 2 at the turn of the 18th and 19th centuries. The yard paving in all the other rooms was laid further towards the east. The surface of the paving was situated in this room 4.73-4.80 above sea level (asl) and it rose in an eastward direction to a height of 5.00 m asl before it began to fall again. |

On the western side of the room was situated a water channel, running in practice parallel with the Council of State building wall. The channel consisted of two rows of unfinished stone, set obliquely against each other. The stones were extremely blackened, with charcoal on top and between them. On the eastern side of the water channel were two rows of small stones before the large kerbstones of the roadway. There were also large stones in the central section, in a zone trending north-south. Most of the stone paving consisted of medium-sized stones. The largest stones were 50 cm in diameter, the medium-sized ones around 17 cm and the smallest around 4 cm. As a result of the fire of 1808, the stones were quite easy to break up. |

The western section of yard paving with its water channel was taken into museum´s collections. The stones were numbered and the structure of the paving documented in photographs and drawings. The recovered yard paving was built in the spring of 1996 for the Helsinki City Museum's Time exhibition.. |
