The narrow streets of Monreal, its quaint Holy Trinity Church, the massive Nepomuk Bridge over the clear flowing Elzbach and the ruins of Löwenburg and Philippsburg castles high above the town are a perfect destination for an excursion in the eastern Eifel. The red and white half-timbered houses nestle closely together in the former cloth-making town. Not only visually is Monreal an excursion destination that relaxes the soul. Café Plüsch with its cosy interior or the former signal box at the gates of the town are perfect addresses for foodies. The highlight for lovers of handicrafts is the pottery in the old school. Hikers get their money's worth on the Monrealer Ritterschlag hiking trail and are rewarded for the sometimes steep passages with wonderful views.

The former Adler Pharmacy is the former manor house of the first and oldest copper yard in Stolberg.

The Germanic bridge over the Kleine Kyll is part of the Kleine Kyll and Punkt 4 mindfulness path on the way and stands for inspiration.

The parish church St. Markus with the high tower crowned by a curved dome and arcade temple was built by the court architect of Archbishop Johann Hugo von Orsbeck, Ravensteyn, as a three-aisled hall church in simple early baroque forms (1709-1723).

The first mention of it as an urban settlement dates back to the 12th century. This is also the time when construction of the town's fortifications began, which were extended and secured until the early 18th century. Remains of this ring of walls and towers have been preserved to this day as architectural witnesses of past centuries.
