As the 'Little Alsace of Texas,' Castroville is known for its historic Alsatian architecture, the landmark Steinbach House, and the scenic Medina River that winds through the heart of town.

Broadband coverage here is inconsistent — some streets have AT&T fiber while others rely on Starlink at $120/month as the only real option. STI's ground-based Air Fiber covers all of Castroville with 400 Mbps for $65/month. No dish. No weather drops. No contract.
