Gelber Stern is one of the most picturesque streets of Hildesheim as most of the buildings are half-timbered houses. Many of them were built on a sandstone base and in some houses the upper floor is larger than the ground floor. One of the most interesting is no. 21, called Waffenschmiedehaus (Armourer's House) dating from 1548 with colourful wood carvings in a renaissance style.[3] Carved inscriptions can be seen in the façades of several houses, e.g. no. 14 - 16 which were built at the end of the 16th century. A complete prayer consisting of four sentences was carved into the façade of house no. 17.
The large building on the corner of Gelber Stern and Brühl is a former hospital which was built in a classicist style 1833–1840. Today it is used as a priests' seminary. The oldest half-timbered house of Hildesheim, which is used as a library today, can be visited in its inner court. It was built in a gothic style at the end of the 15th century.[4]
