Scott, a citation in the Saint Paul History and Area Business Index describes Market Hall as being on 7th Street West, at the northeast corner of Saint Peter Street. The index also shows several articles about the Market Hall, at least one of which containing an illustration. However, the articles themselves are on microfilm, so any further investigation would require a $15 service fee as explained in the attached document regarding the library's policy on service and delivery fees. 

If this is something you wish to proceed with, simply let me know, and an invoice will accompany copies of any relevant information found.

(As this is a zero budget project, I must forego the service).
