The Elbbach's broad lower reaches follow a tectonically created fault (Elzer Graben) which stretches northwards into the community of Dornburg.

Overlying these in turn are layers of Ice Age loess deposits, which have laid the basis for fruitful agriculture.

The village on the important strata publica, or Hohe Straße ("High Road") between Frankfurt am Main and Cologne was in the Middle Ages at first under royal rule.

The document attesting this, which guaranteed the Elz townsmen in the Late Middle Ages their freedom was effected by Archbishop of Trier Jacob I of Sierck.

Until the 13th century, Elz belonged with some 20 other places to the parish of Dietkirchen, which with its Romanesque basilica was widely known throughout the Lahn valley.

The foundation stones were laid on 27 June 1852, on the occasion of which a celebratory Mass by Bishop Peter Josef Blum and Vicar-General Klein was said.

A stone plaque with the year 1852 over the sandstone architrave block facing Pfortenstraße still witnesses this event.

Since the German Bishops' Conference in 1872 moved the festival, the third Sunday in September has been set as the deadline for the kermis.

The local recreation area "Anlagen" lies not far from the middle of the community, north of the parish church on a bank towards Malmeneich.

The "Anlagen" nowadays offer, besides the structuredly laid-out tree learning path, a miniature golf course and a playground.

The community is also known countrywide for its Elzer Berg (mountain) on the notable drop in elevation from the Lower Westerwald into the Limburg Basin.

As traffic regularly backs up here, the plan for the long-distance federal roads has identified a bypass for Elz as an urgent need; the price for such work will be €12,600,000.

From the regional station at Limburg, the cities of Gießen, Koblenz, Frankfurt am Main and Wiesbaden may be reached directly.
