Description of the Flag
Per fess gules and argent.
Divided horizontally into equal parts red over white.
T.F. Mills, 19 October 1997
Symbolism of the flag
There are at least two theories on the origin of Solothurn's colours. 
One holds that they came from the vexillum of the ancient Roman 
Legion of Thebes which was massacred in Helvetia in 302.  St. Ursus, 
the patron saint of Solothurn, was allegedly an officer of the 
legion.  Less likely, Solothurn adopted the colours of Austria (as 
did Schwyz and Unterwalden).
T.F. Mills, 19 October 1997
The name "Solothurn" comes from Celtic "Solodurum". The ending "-durum" means gate.
History of the Flag
According to legend, Ursus was an early Christian who proselytised 
the Solothurn region.  He was persecuted and eventually decapitated 
on the Aare River bridge, and his body thrown into the river (see history of Swiss flag).  But 
the body swam ashore, picked up its head, and walked to its burial 
place.  Thus did Ursus become the patron saint of the city.  The seal 
of the city has always depicted St. Ursus, and as early as 1394 the seal 
contained a red and white background identical to the current flag, 
so these are regarded as St. Ursus' colours.  Solothurn became an 
independent state in the empire in 1447, and was admitted to the 
Swiss Confederation on the same day as Fribourg in 1481.  This was 
done over the objections of Obwalden, whose flag at the time was 
identical.

Flaggen are vertically hoisted from a crossbar in the manner of gonfanon, in ratio of about 2:9, with a swallowtail that indents about 2 units. The chief, or hoist (square part) usually incorporates the design from the coat of arms – not from the flag.  The fly part is always divided lengthwise, usually in a bicolour, triband or tricolour pattern (except Schwyz which is monocolour, and Glarus which has four stripes of unequal width).  The colours chosen for the fly end are usually the main colours of the coat of arms, but the choice is not always straight forward.
Knatterfahnen are similar to Flaggen, but hoisted from the long side and have no swallow tail.  They normally show the national, cantonal or communal flag in their chiefs.

a (baroque) shield in the centre of the flag. These decorative flags had been used until WWII and then
somewhat forgotten in preference of the current cantonal flags. [Today they are being
produced again, see right image]
