Above the municipality, the watchtower is the highest viewpoint in the vineyards. It was built using stones from the old Königsstuhl between Nierstein and Lörzweiler, where in 1024 the conclave of princes elected Conrad II as the first Salian to sit on the German throne. Saint Kilian’s Catholic Church, which can be seen far afield, perched upon a hill rising up at the Rhine valley, defines Nierstein’s skyline, although this is also marred somewhat by a former malthouse’s tall buildings. Plans are, however, afoot to have the old malthouse torn down and the lands redeveloped, thereby also opening the old "Dalberg-Herdingsche Schloss" on the malthouse’s grounds – or at least the residence’s house chapel, which is worth seeing – back up to visitors.
