: What were the stipulations when West Germans or individuals from Western

: over for the day or could they stay a few days?

In 1987 as a UK passport holder I crossed from West Berlin to East Berlin
for a day trip - travelling on the S-Bahn to Friedrichstrasse station - on
the strength of a day visa issued by the GDR authorities at the border
control point in the station.

If I remember correctly, it was also compulsory to exchange a certain sum in
West German marks for East German currency - I forget exactly how much.
