Summary

We study visible Lagrangian submanifolds, that is, Lagrangian submanifolds whose projection under a Lagrangian fibration has positive codimension. We show that projections of visible Lagrangians are affine subspaces of rational slope. We give some examples and explain how a visible Lagrangian can intersect the toric boundary.
