Shadows-on-the-Teche, Historic plantation house in New Iberia, Louisiana, United States.

Shadows-on-the-Teche is a two-and-a-half-story, sixteen-room red brick house built in 1834 for planter David Weeks and his wife Mary, set 20 feet above the Bayou Teche in New Iberia. Its south front has eight full-height Tuscan columns of white-plastered brick supporting a second-floor gallery, with three pedimented dormers on the gabled roof.

The house was built in the early 1830s for a sugar planter and remained in the family across several generations. It changed hands and eventually became a public historic site open to visitors.

The name comes from the trees that cast shadows on the nearby water. Visitors moving through the rooms encounter traces of how multiple generations lived and worked across many decades.

The site is accessible on foot and the main rooms are fairly easy to navigate through. Comfortable shoes are recommended since exploring the different floors and rooms takes time and involves some stairs.

The house museum holds about 17,000 items, including photographs and letters. Writer Henry Miller was a regular guest at the evenings William Weeks Hall hosted here, and he set his story The Air-Conditioned Nightmare in the residence.
