From the churchtower at Saint Michael's, the following places can be seen: to the southeast, the Soonwald (a heavily wooded section of the west-central Hunsrück) with the Koppenstein castle ruin; to the south, the Lützelsoon (a little outlier of the Soonwald); to the southwest, the Idarkopf and the Erbeskopf (mountains, the latter of which, at 816 m above sea level is Rhineland-Palatinate's highest point); to the northeast, the area around Kastellaun; to the east, the district seat of Simmern.

Aerial photographs of Kirchberg clearly show how the town has developed in stages: The outlying centre of Denzen (from the Celtic Dumno), lying in a hollow to the northeast, had its beginnings in a pre-Roman settlement; the town’s east end was a military base on the Roman road from Trier over the Hunsrück to Bingen am Rhein and Mainz, nowadays known as the Via Ausonia (Ausoniusstraße in German).

Around the oval of this former town wall arose residential neighbourhoods, schools and sport facilities, allotments and industrial parks in the time that followed.

Archaeological finds make it clear that by 400 BC, the Treveri, a people of mixed Celtic and Germanic stock, from whom the Latin name for the city of Trier, Augusta Treverorum, is also derived, had settled here.

In 368, the Roman poet and educator Decimius Magnus Ausonius also mentioned Dumnissus in his poem Mosella, which contains a poetic description of his trip from Bingen by way of the Hunsrück to Neumagen and Trier.

In 995, King Otto III bestowed upon Count of the Trechirgau Bezelin, the forefather of the Gau-comital family Berthold-Bezelin, the hitherto royal estate of Denzen (praedium Domnissa).

In 1074, the family then transferred the eastern half of this holding, along with the village of Denzen, to the Ravengiersburg Augustinian Canonical Foundation, which the counts had endowed.

A further ruling allowed the Evangelical parish to use Saint Michael's Church, as before, until its own church was ready for use, and further still, it allowed the Catholic parish to be guests at the Friedenskirche as long as thorough restoration work was being undertaken at Saint Michael's and its tower and until preliminary archaeological digs by the Koblenz Office for Prehistory and Protohistory (Amt für Vor- und Frühgeschichte, Koblenz) were over.

Building III was a three-naved, flat-ceiled basilica with a semicircular apse built sometime before 1050, likewise with a baptismal facility and a west gallery.

Among the things inside the church that are worthy of note are the stonemasons’ marks in the nave, found on pillars and ribs, the sandstone pulpit from about 1490, grave memorials from the 15th to 18th century with Catharina von Hoising's well known tomb in the quire (Master Johann von Trarbach, after 1577), the baptismal font with the combined coat of arms of the families who put forth the endowment (earlier half of the 18th century), the High Altar, the two side altars and the design of the organ pipe ranks from the latter half of the 18th century.

On the west side stands the Baroque building of the former Piarist monastery from 1765, which today serves as a rectory and a community centre.

The baptismal font, carved from a stone worked in Roman times and unearthed during the digs under Saint Michael's, is a gift from the Catholic parish.

The Nikolaus-Kapelle – or Saint Nicholas’s Chapel – that stands today in Kirchberg-Denzen, with its Romanesque quire tower, looks back on a long tradition: An earlier building had until 955 John the Baptist as its patron.

The municipal election held on 7 June 2009 yielded the following results:[3] Kirchberg's mayor is Werner Wöllstein (FDP).

[1] The German blazon reads: Das Stadtwappen zeigt in einem spätgotischen Rundschild auf rotem Grund winkelmäßig angeordnet abwechselnd je 16 in gold und blau gehaltene Quadrate.

The town's arms might in English heraldic language be described thus: Gules a chevron countercompony Or and azure throughout, in base a crown of the second.

The chevron countercompony (that is, chequered in two rows) refers to the “chequy” arms borne by the Counts, with the squares here in the same tinctures as they were in theirs.

Foreseen for the railway line, the Hunsrückquerbahn (Langenlonsheim-Stromberg-Rheinböllen-Simmern-Kirchberg-Hermeskeil), is at least partial reactivation to serve Frankfurt-Hahn Airport, although for the time being it still lies idle.
