The architectonical look of the town of Lüen is a good example of how the Latin and the Germanic cultures intermixed in the Grisons: in Lüen there is a mixture of houses built with block of woods (typical of the so-called Blockhäuser imported in the area by the late Walser migrations) and of houses built of stone (typical of the indigenous Romanic populations).^[6] The train station of Lüen-Castiel was built in 1914. The romanesque church of St. Zeno was built in 1084. The interior is covered with gothic paintings from the studio of the Waltensburger Master, from the mid 14th Century. Interior of the Church:
