It is named after the original owner, Knight Bohuchval Valkoun of Adlar, who owned it from the beginning of the 17th century.

In 1601 it was bought by Kašpar Kaplíř of Sulevice, who was executed on the Old Town Square.

[2] Upon Santini's death, a renowned goldsmith bought the house and built up the third floor.

At the same time, a careful reconstruction of the whole property commenced, and the authentic wooden ceilings, ribbed vaults, wall fresco paintings and an original porcelain cocklestove have been retained in what is now a hotel.

Of note are exquisite details such as a Medusa relief over the left entrance, a cartouche and a small head next to it beyond the right entrance, an oval cartouche with a painting of Virgin Mary and the Holy Trinity above the second floor windows or the functional sun dial placed on the façade in the inner block.
