First written evidence about house No. 27 in Radniční Street dates back to the year 1459. The stone house had probably been on its place already in the 14th century according to the construction-history research. The original flat-ceiling cellar made of stone may have been its remains. The appearance of the Gothic crosswise back wing of the house, which links to the crosswise wing of neighbouring house No. 25, remains uncertain. Two thick arches enclosed in a wall were uncovered in its west peripheral wall (today leading to the courtyard) during the archaeological work in 1993/1994. A club-shaped fragment of the large storage vessel made of clay with the mixture of graphite and a fragment of the relief unglazed stove tile ornamented with the motive adoration of the Magi come from the south arch brickwork. The storage vessel and the stove tile were made during the 15th century. The arcade was probably walled in the late 15th century or the early 16th century. The arcade wall must have been built even earlier.
At the turn of 1993/1994 some workers from the Český Krumlov Local History and Geography Museum observed clearing out of the house interiors. Archaeological discoveries of the late Middle Ages and Modern Period come from vault filling on the first floor and mezzanine - a wooden spoon, a piece of leather pouch, some pottery, etc. Several fragments of the late Gothic stove tiles with cut front, vessel fragments - technical pottery, etc. come from the ground-floor entrance. A collection of discoveries dating from the 15th century come from the vault filling above the back wing of the house opened into the courtyard. A collection of Renaissance stove tiles was successfully gained during taking the open-hearth kitchen body to pieces in the house mezzanine. A large number of technical pottery was discovered almost everywhere in the house.
The archaeological probe of the house cellar, where a functional well was found, was done at the same time. Besides several fragments of Renaissance stove tiles, some unique Renaissance portable kilns owned by Sebald Matighofer of Rožmberk, a silver acid-test examiner, were found in one of the filling layers under the boulder floor of the east raised cellar part.
