The church of Lena was built around the year 1300 and consisted of nave, tower and vestry. Wall paintings were added in the early 16th century. The church's eastern part is a chapel where members of the family Bielke are buried. The altarpiece was made in 1491 by carpenter Lars Germundsson in Enköping.
Next to the near vicarage are ruins from the late Iron Age, namely, five burial mounds, a large number of stone formations and some runestones.

House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
