St. Markus Church at Longsdorf
St. Markus church at Longsdorf, south of Vianden, belonged to the Vianden Trinitarians. It is a church with two naves, a type of church fairly common in the Our valley around Vianden. The inner rectangle inco1porates the choirs. Two octagonal pillars separate the two naves, while the choir is divided into three parts by two round columns. The two naves and the three choirs architecturally merge into a harmonious unity. A hermitage adjoining the church allowed the hermit to see the altar and follow the church services through a quaint little window.
