Merzhausen is the smallest municipality in the local area with the highest population density, which is also higher than that of Freiburg.

[4] Merzhausen was first recorded in 786, when the original land owner Heimo Güter gave it away to the Abbey of Saint Gall.

Eventually, the land pass over to the newly created Grand Duchy of Baden, alongside all of Breisgau.

Merzhausen's coat of arms depicts on a silver (white) background a black bear, the symbol for being part of the St Gallen cloister, which holds in front of itself the crest of the Schnewlin family.

Every Saturday, there is a weekly market which is located in the Marktplatz in front of the Forum Merzhausen and is open from 8am-1pm.

Elsewhere, predominantly small and medium-sized companies in the area of trade, crafting and servicing as well as freelance professions within Merzhausen.

Additionally, a free information brochure is released every two years about the municipality of Hexental in the A + K publishing house.

Citizens of Merzhausen are allowed to help as volunteer firefighters in the Unterstadt division of the Freiburg fire service.

In addition, the bus line 7208, maintained by Südbadenbus, operates between Bad Krozingen and Freiburg train station via Vauban.

[13] In the middle of town, there is a sports hall with a beach volleyball arena as well as at the renaturalised Dorfbach there is a wading pool.

Merzhausen is the starting point for the historical Bettlerpfad (Beggar's Path), one of the old connections, which is still used to this day as a public footpath, to Freiburg via Staufen im Breisgau and Salzburg to Badenweiler.

The village also has a lot of breathtaking nature, so much so that in 2015 successful breeding pairs of long-eared owl have been observed in a garden on the Schlossweg and been documented.
