TITLE: Non-metric topological continua
QUESTION [7 upvotes]: What important results hold for non-metric continua, or where can I find a survey of such results?
There are three definitions of a continuum around: a non-empty topological space that is
(1) connected compact metric, or
(2) connected compact Hausdorff [e.g., General Topology by Willard], or
(3) connected compact [ProofWiki].
I am interested in non-trivial properties commonly known for definition (1) that have been found to also hold for definitions (2) or even (3).
I have asked this question on math.stackexchange but did not get any answer.

REPLY [2 votes]: The non-cut point existence theorem is a good one. 
Wilder proved sometime around the 1930's that every type (1) continuum has at least two non-cut points.  This was later generalized for type (2) continua sometime around the 1960's by Whyburn, and finally, for all (type (3)) continua in 1999 by Honari and Brahmanpour. 
Most results do not proceed this way, I must warn you.
Usually either (a) there is a non-metric counterexample, or (b) the original proof for metric continua "obviously" does not require metrizability and so applies to more general continua.
