The cinema Lichtburg in Essen opened in 1928 with 2.000 seats. It was destroyed in 1943 and reopened in 1950. The Lichtburg has still today one hall with 1.250 seats. A second smaller hall with 150 seats is called Sabu - in memory of the Indian actor Sabu (1924 - 1963), famous from The Thief of Bagdad (1940).
Unfortunately the stamp isn't left on the card, so I can't identify the date/year of the postcard. I think the picture was made in the early 1930s.
So the Lichtburg is one of these old film palaces from the great 1920s era, of corse a listed
monument and really worth seeing. There can still played movies in 70 mm,
for instance the Tarantino's The Hateful 8.
A postcard maybe from the late 1960s showing Kettwiger Straße view to the Burgplatz with cinema Lichtburg left.
