Trinity (Christians) = Trimurti (Hindus)? I have heard about the concept ot Trimurti in Hinduism Wiki. One for construction (Brahma), one for protection (Vishnu) and one for destruction (Shiva). And somehow I feel it is related to Trinity in Christianity. Are there any relations?
One could do a great deal worse than quote another answer:


  There are several heresies that one needs to be careful of when discussing a topic such as this. For example, Modalism which declares that God is not three distinct persons, but that He merely reveals himself in three different forms. Or, Arianism which declares that Christ and the Holy Spirit are creations of the Father and not one in nature with Him. Or Partialism which declares that the Father, Son, and Holy Spirit are not distinct persons of the Godhead, but are different parts of God each composing a third of the divine.


Each of the different views of the Trimuti within Hinduism falls into one or more of those camps. My analysis (based on Wikipedia) may not be complete, but I posit this:&mdash;


Sauram: modalism
Vishaivism: Arianism
Shavism and Smartism: partialism


So: no, apart from both the Trinity and Trimurti being "three", there are no similarities. Specifically, the Trimurti denies that the three gods are wholly three and wholly one.
