What they say on their website:

Emmanuel Baptist Church has a deep and rich history in the city of Albany. Emmanuel began in 1810, then known as the Particular Baptist Church. Reaching membership of 327 in 1834, the congregation outgrew a theater where they had been worshipping, so they built a new place of worship, called the Pearl Street Baptist Church. The Pearl Street Church prospered and grew and by 1866 it had outgrown its pews.

A new and larger church building was needed, closer to where people lived and away from the expanding commercial area on Pearl Street. The site at 275 State Street was secured in 1869 and a new edifice erected. At the dedication, held in February 1871, the present name Emmanuel was adopted. This has been the congregation’s home ever since.
