Jablonec nad Jizerou (German: Jablonetz an der Iser) is a town in Semily District in the Liberec Region of the Czech Republic.

[3] An already medieval built-up area, which is probably to be found in the vicinity of the Church of Saint Procopius (originally wooden, from bricks since 1777 thanks to the support of Ernst Adalbert of Harrach) had more diffusive character, also the area from the second half of the 18th century was almost out of order on the slope of the valley.

[3] The only organizational factors were contour lines and parcels of land, a completely non-agricultural dwelling were chaotically centered on the link between the church and the mill.

[4] Today among the new buildings from the turn of the 19th and 20th centuries and from the interwar period are sporadically preserved timbered houses.

Jablonec nad Jizerou is the terminus and start of the railway line from/to Martinice v Krkonoších.

[9] The main landmark of Jablonec nad Jizerou is the Church of Saint Procopius.
