Honors and tributes flowed to Bell in increasing numbers as his most famous invention became ubiquitous and his personal fame grew. Bell received numerous honorary degrees from colleges and universities, to the point that the requests almost became burdensome. During his life he also received dozens of major awards, medals and other tributes. These included statuary monuments to both him and the new form of communication his telephone created, notably the Bell Telephone Memorial erected in his honor in Alexander Graham Bell Gardens in Brantford, Ontario, in 1917.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was the Bell Telephone Memorial constructed?
1917
