House No. 176/4 At the Virgin Mary from the year of around 1360 (later also called At Our Nice Lady) is a very narrow ( 3.28 m!), biaxial, three-storey house, set in a crooked Seminarska street this irregularity shows a very old origin of the street and houses located there. Building history of this house is uncertain, lay-out of the city, however, shows that the house was developed by a supplementary division of a larger neighbouring building. Current look of the exterior and interior is a result of modern modification of late classicist facade.
With its width of only 3.28 metres, the Clementin Old Town Hotel is the narrowest preserved house in Prague. Its origins date back to the year 1360. All of its elegantly furnished rooms are air-conditioned and come equipped with a satellite TV and a tea and coffee maker. An internet station is available for free in the lobby. The hotel's cafe features a charming terrace on the narrow Seminarska street.
